CNC machines rely on hard tooling to accurately position and hold parts like this freshly carved neck.

Jol Dantzig's Esoterica Electrica: Tooling Up

cnc machine rely

Even CNC machines rely on hard tooling to accurately position and hold parts like this freshly carved neck.

Those of you foolish enough to have read my previous writings know how much i adore guitars and the bric-a-brac that goes along with them. since one of my favorite things about building is the design and execution of hard tooling, I've also subjected you to my pontificate on tools that are used to make instruments. without these nifty little (and not-little) items your guitar might never have been bore. In fact, Most every part of the Process relies upon tooling of some kind.

As essential and ubiquitous as it is, hard tooling is one mysterious aspect of guitar making that doesn't get much screen time. its younger sibling, CAD/CAM (computer- aided design and computer-aided manufacturing) hogs most of the publicity nowadays, probably because of its digital status. but it's interesting to note that even cnc machinery-the automated equipment that runs on CAD and CAM programs-can't function without hard-tooling design.

tooling, which includes fixture and Jigs, are devices that hold or move parts as they are being machined. It can be merely to clamp a single part, or it can hold many- as in the case of a CNC machine. Tooling can bee stationary while cutters, sanders, or drills move into or over the part being done. Some tools have multiple stages and re position for a series of steps. parts can be indexed (located) manually or via mechanical means. tooling can be as simple as a block of wood clamped to a saw's fence, While other fixtures and jigs can be complicated and even programmable to set up multiple operations in succession.

When we used hand tools like chisels, the parts being worded are usually held in a vise  or clamped to a workbench with "dogs" that keep the piece steady. This allows the control of the cut to be determined by the worker's hands and prevents the part from skating away. if you've ever tried to saw a small piece that wasn't held down, you know how difficult that can be. In a way, the bench dog and the vise are the first and most primitive kinds of hard tooling.

When I Visit a workshop or factory of any kind, I admire the tooling more than the items that are being made with them.

In the modern incarnation, CNC machining can use pneumatic-cylinder clamps or a vacuum device for clamping power. These fixtures hold the work in the same place each time so the machine can repeat its work blindly. Eventually, computer-milling stations will see the work and be able to adjust their movements accordingly—just like a human worker might. But for now, most fixture is analogous to T-ball, where one item is held in place and the machine swings the bat.

The mobile type of tooling is one of my favorites. This includes forms that determine the shape of a part to be cut. It can be done by making an outline template that’s affixed to the raw part, and then running the raw part against a router or sharper. Or conversely, a hand router can be moved around the template. A rub bearing or locating pin feels along the edge of the template while the router bit cuts the part to shape accordingly. The part can be located by eye using alignment marks, or with pins that fit into holes in the part. (If you look closely at some early Fender guitar bodies, you can see the small, filled-in locating holes.)

I’ve made dozens of these tools over the years from plywood, phenolic composite, and aluminum. For prototyping purposes, you can even use double-sided tape to hold a part on the form!

One of the most challenging things about devising excellent tooling is building adjustments right into them. I’ve watched entire systems—built on the premise of accuracy—come crashing down when the final parts don’t fit each other. When dealing with wood, things change. If you don’t build tooling that allows for variable materials, each tool will compound the inaccuracies of the ones that came before. And this can leave you with a lot of scrap reports to fill out.

A well-designed and flexible piece of tooling is a beautiful thing to see. When I visit a workshop or factory of any kind, I admire the tooling more than the items that are being made with them. Almost anyone can imagine and draw a guitar form, and lots of people can hack out an instrument. A good engineer can devise a system of tools that looks good on paper, but fails in the real world. In my estimation, it’s a clever crafts person that dreams up and builds fine tooling that works.

Tormach unveils a truly capable desktop CNC machine

Tormach unveils a truly capable desktop CNC machine

The maker community is turning into a quickly-growing movement, as shown by the ever-expanding Maker Faires popping up worldwide. This last weekend was World Maker Faire in New York, where Tormach, a company known for making small, affordable CNC machine tools announced an even smaller, more personal mill, the PCNC 440.

Following in the footsteps of recent desktop CNC (computer numerical control) machines like Carvey and X-Carve, the PCNC 440 mill is designed to fit on benchtops, and lower the barrier of entry to real CNC. What’s different is that this machine is less like a router – it’s truly a CNC mill – allowing travel of 10 x 6.25 x 10 inches / 25.4 x 15.9 x 25.4 cm (X x Y x Z).

Real Machining

With an R8 spindle, a spindle speed of up to 10,000 RPM and quick-change tooling, Tormach has taken cues from its industrial brethren, but managed to make its machine more approachable. Like major industrial machines, both CAD (computer aided design) and CAM (computer aided manufacturing) software are needed to create a part on the PCNC 440. Being that these are often expensive and cumbersome to learn, Tormach has partnered with Autodesk to provide a free year-long seat to a commercial version of Fusion 360 (CAD/CAM) with the purchase of this machine.

Because the PCNC 440 requires traditional software workflows to start cutting parts – unlike other desktop-style CNCs and 3D printers that allow a drag-and-drop file workflow – to some, this may be where the 440 falls short of other maker-oriented cutting machines.

"CNC Machining still does not have a one button print function like many of the desktop 3D printers," Tormach’s product marketing manager Andy Grevstad explains. "The PCNC 440 is easily the most approachable CNC mill for beginners, but you’ll still need to invest some time to learn machining techniques and CAD/CAM programming skills. While it lacks the instant gratification of a 3D printer, it is a much more capable and rewarding technology in many aspects."

Also, like its bigger brothers in the industrial world, this machine can cut everything from wood and plastics to real metals like aluminum, steel and even titanium, with precision – although a bit slower. In comparison, one of the smallest industrial machines, the Haas MiniMill, uses a 7.5 HP spindle, compared to the PCNC 440’s ¾ HP spindle, but a MiniMill starts at US$34,995, while the 440 starts at just $4,950.

"[The PCNC 440] is more for small prototype work, inventors, educators, and specialty manufacturing," Grevstad says. "There is a need for CNC milling technology outside of traditional manufacturing environments and I think that the PCNC 440 fills that role."

Still for the Maker

What the machine lacks because of complexity, it gains in approachability. Tormach has developed PathPilot, the company’s machine control system which is rooted in the open-source Linux CNC project. This software reads any industry-standard G-code and also has some conversational programming for those that like to edit and tweak things on the fly.

While Tormach makes two other larger CNC mills (the PCNC 1100 and PCNC 770) and a CNC lathe, the PCNC 440 keeps the tinkering audience in mind. It weighs just 450 lb (204 kg), has a compact footprint of 42 x 36 inches / 106.7 x 91.4 cm (W x D), and runs on 115 VAC, single-phase power.

There's more on the way for the PCNC 440, too – Tormach plans to release a power drawbar, an automatic tool changer, and a 4th axis sometime in early 2016, making this thing a tiny, all-encompassing manufacturing center.

Currently, the PCNC 440 is available for pre-order only, due to ship in November. Grevstad is sure we will continue to see new advances in many facets of affordable digital tools for things like at-home manufacturing. "It’s an exciting time for makers and those that want to make things," he says.

What is The Use of Cnc Machines

Computer Numerical Control 

CNC (computer Numerical control) is a Method for controlling machinery with a computer, it can allow precise and repeatable control of over a larger number of axes then a human could directly control.

CNC machines usually work in one of two ways:

1.Removing material from stock-mills and lathes
2.Precisely depositing material-3D printer such as the RepRap & Makerbot

What is the use of cnc machines

What Does It Stand For
Engineers Love initial-isms, Mostly because they make saying long or complex phrases more efficient. In this case engineers coined the term CNC didn't feel like repeating computer Numeric Control Over and Over again.

How Does It Work?
If you breakdown the phrase you can glean the function of this technology. At Its Most basic a CNC machine manipulates an end effector in an established coordinate system to perform a task set about by the operator who controls it using a computer. CNC machines are typically used in an  industrial setting; however, a printer is a good example of a nearly ubiquitous CNC machine.In order for a printer a deposit ink on a Piece of paper, it needs the instructions from an operator.The operator tells the computer what they want to print and the computer sends that information to the printer in a way the printer in a way the printer can understand. There is an unbroken thread from operator's thought to information on paper and this is the same as fabricating a part. The CNC machine allows the operator to talk through the computer to the mill, Lathe or printer to accomplish a task Quickly and with precision.

What Good Is It?
You can trace back a vast majority of the products you encounter to CNC machining. Whether they were made from CNC machines, prototypes on CNC machines, Or The tooling for making the product was made by a CNC machine, if It is a Physical product chances are very good CNC was involved.

It is an amazing technology. I got into a Little more detail here if you are interested.

Laser cutting Machine Technology

Laser cutting Machine Technology 

Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the material or the laser beam generated. A typical commercial laser for cutting materials would involve a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas,[1] leaving an edge with a high-quality surface finish. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials.

In 1965, the first production laser cutting machine was used to drill holes in diamond dies. This machine was made by the Western Electric Engineering Research Center.[2] In 1967, the British pioneered laser-assisted oxygen jet cutting for metals.[3] In the early 1970s, this technology was put into production to cut titanium for aerospace applications. At the same time CO2 lasers were adapted to cut non-metals, such as textiles, because, at the time, CO2 lasers were not powerful enough to overcome the thermal conductivity of metals

Power Consumption

The main disadvantage of laser cutting is the high power consumption. Industrial laser efficiency may range from 5% to 45%.[13] The power consumption and efficiency of any particular laser will vary depending on output power and operating parameters. This will depend on type of laser and how well the laser is matched to the work at hand. The amount of laser cutting power required, known as heat input, for a particular job depends on the material type, thickness, process (reactive/inert) used, and desired cutting rate.

Amount of heat input required for various material at various thicknesses using a CO2 laser [watts]

		Production and cutting rates

The maximum cutting rate (production rate) is limited by a number of factors including laser power, material thickness, process type (reactive or inert,) and material properties.

Common industrial systems (≥1 kW) will cut carbon steel metal from 0.51 – 13 mm in thickness. For all intents and purposes, a laser can be up to thirty times faster than standard sawing.

CNC Router Machine

CNC Router Machine 
A CNC router is a computer controlled cutting machine related to the hand held router used for cutting various hard materials, such as wood, composites, aluminium, Steel, plastics, and foams. CNC stands for computer numerical control. CNC routers can perform the tasks of many carpentry shop machines such as the panel saw, the spindle Mulder, and the boring machine. They also cut mortises and tenons.

Drawing of Table Top Diy CNC Router, Silver: Iron Red: Stepper Motors , light Brown MDF, Dark Brown: Hard Wood.

A CNC router is very similar in concepts to a CNC milling machine. instead of routing by hand, tool paths are controlled via computer numerical control. The CNC router is one of many kinds of tools that have CNC variants

Cnc Router Machines 

A CNC router typically produces consistent and high-quality work and improves factory productivity. unlike a Jig router, the CNC router can produce a one-off as effectively as repeated identical production. Automation and precision are the key benefits of cnc router tables

A CNC router can reduce waste, frequency of errors, and the time the finished product takes to get to market

Applications

A CNC router can be used in the production of many different items, such as door carvings, interior and exterior decorations wood panels, sign boards, wooden frames, moldings, musical instruments, furniture, and so on. in addition, the CNC router helps in the Thermos forming of plastics by automating the trimming process. CNC router can help ensure part repeat ability and sufficient factory output.

Overview of CAM (computer-aided manufacturing)

CAM software makes the CAD drawing/design into a code called g-code. This code the cnc machine can understand. in short, CNC technology is not very complicated. it is a tool controlled by a computer. it only becomes more sophisticated when considering how the computer controls the tool. The illustration shows what a bare bones CNC machine might look like without its controller.

Sizes and configurations of router

CNC routers come in many configurations, from small home-style D.I.Y. "desktop" like K2 cnc, to large industrial CNC routers used in sign shops, cabinet making, aerospace and boat-making facilities. Although there are many configuration, most CNC router have a few specific parts: a dedicated CNC controller, one or more spindle motors, servo motors, stepper Motors, Servo amplifiers, AC Invert-er drives, linear guides, ball nuts and a work space table or tables. in addition, CNC router may have vacuum pumps, with grid table tops or t slot hold down fixtures to hold the parts in place for cutting. CNC routers are generally available in 3-axis and 5-axis CNC formats. Many Manufacturers offer A and B Axis for full 5 Axis capabilities.

Controlling the machine

The CNC router is controlled by a computer. co-ordinates are uploaded into the machine controller from a separate CAD program. CNC router owners often have two Software applications-one program to make designs (CAD) and another to translate those designs into a 'G-code' program of instructions for the machine (CAM). As with CNC Milling machines, CNC router can be controlled directly byy manual programming, and CAD/CAM opens up wider possibilities for contouring, speeding up the programming process and in some cases creating programs whose manual programming would be, if not truly impossible, certainly commercially impractical.

Types

Wood

Main article : CNC wood router

A CNC wood router is a CNC Router tool that Creates objects from wood. CNC stands for computer numerical control. The CNC works on the Cartesian coordinate System (X,Y,Z) for 3D motion control. parts of a project can be designed in the computer with a CAD/CAM program, and then cut automatically using a router or other cutters to produce a finished part.The CNC Router is ideal for Hobbies, engineering prototyping, product development, art and production work.

Metal

Main article : Milling Machine

Milling is the machining process of using rotary cutters to remove material from a workpiece advancing (or feeding ) in a direction at an angle with the axis of the tool It covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations it is one of the most commonly used processes in industry and machine shops today for machining parts to precise sizes and shapes.

How many type of Cnc Machine

CNC Machine & laser Machine.

Q. How many types of cnc ( Computer Numerical control ) machines are there ?

As many as your heart Desires; if your production process needs a degree of motion (or other control ) and you can put a computer-controlled sensor and actuator on it, you have a CNC machine.

Five and six-axis machines can really blur the traditional distinctions between "lathes" and "horizontal mills", but That's all the better for production Flexibility.

There are basically five different types of CNC machines:

1.CNC Plasma Cutting Machine

2.CNC laser Cutting Machine
3.CNC Milling Machine
4.CNC Router Machine
5.CNC Lathe Machine

All the Five Types of machines have their own applications in a verity of industries. Let's find out which types of industries are using such machines and what the application of each of the machine is.
when CNC was first invented it was a technology that was adapted to fit existing tools but there are also many machines which are created for the sole purpose of being CNC machines.

Milling Machine 

Milling machines are often retrofitted with CNC technology. This process involves removing all the mechanisms built into the machine to make it easy for a human to operate, Such as Hand Wheels and DRO (Digital Read Out) electronics.

The machine will usually have its old lead screws replaced with new very high accuracy ball screws and various new mounts built for mounting the actuators to the machine.

Lathe

just like the milling machine, lathes are also commonly retrofitted with CNC technology in the exact same way.

Machines that are Custom Built For CNC operation

Router

CNC Router are a very common piece of machinery you will see a lot when learning about CNC. These are machines built exclusively to be operated by CNC technology and have no human interface other than through the computer.

Routers are generally for producing larger work and more commonly built with the idea of cutting wood, plastics and sheet metal in mind. Router also are most commonly found in a 3 axis setup (X,Y and Z.) Thiz set up will allow cutting of basic profiles and 3 dimensional relief machining. there are also CNC router which are 4, 5 or even 6 axis, these machines are more suited towards cutting more complex shapes or prototype models.

Milling machine 

There are many milling machines today which were built specifically for CNC as opposed to being retrofitted at a later stage.Some of these machines can be absolutely massive and have built in tool changers, auto-feed mechanisms for loading in material and various electrical sensors for safe monitored cutting.

CNC plasma Cutter 

CNC plasma cutters are very similar to CNC routers in size and setup, however plasma cutters don't require as much of a powerful set because as opposed to dragging around a spinning tool in material they fly above the table with a plasma torch.plasma cutter are made for cutting 2 dimensional profile shapes into sheet metal.

Cnc laser cutter

CNC laser cutters follow the same principle as the plasma cutter. However laser cutter use a much less destructive force than a plasma torch-A laser. laser cutters are often good for cutting wood, plastic and metal. Each will need a different strength of laser suited for the material.

3D printer

A 3D printer or 3 Dimensional printer uses a similar set up as a CNC router or laser cutter, except it uses a plastic extrudes. This plastic extrude pushes out hot plastic through a tiny hole and slowly, by layer deposits enough plastic to build up a completed part.

Pick and place Machine

A pick and place machine again uses a similar set up as a cnc router or laser cutter. This time there a multiple small nozzles, that pick up electrical component down. hence the name pick and place.
pick and place machines move very quickly and are used to palace the many hundreds or thousands of electrical components that make up Services such as computer motherboards, phones/tables, and pretty much everything else that has a printed circuit board.

Many types of CNC machines exists out if which very few are know such as

1.Retrofitted Machine which includes machines like Milling Machines, Lathe Machines Etc. Which uses rectification with CNC Technology.

2. Custom Built Machines For CNC operation: it includes machines like Routers, Milling Machines, CNC Plasma Cutter, 3D printer, Pcik and Place Machines Etc.

If a tool exists you can Probably run it with CNC.

1.Lathes 2. Mills  3.Router  4.grinders 5.welder 6.Torch & plasma cutters 7.Water Jet 8.laser 9. Plotters/paper cutters  10.measuring  11. 3 D printers

There are Probably some cake decoration a Machine

A Q & A with artist Susanna Crum on the opening of calliope Arts

[ the above images is "breaking the loop (the loop)" by Susanna crum.]

print markers Susanna crum and Rudy salgado Jr. are the owners of the brand new calliope Arts print marking studio and gallery ( calliope-arts.com). It is something they have been thinking about and planning for since their college days.

LEO: you recently opened calliope Arts as a  collaborative space. please explain how it works.

Susanna Crum: calliope Arts opportunities for artists in four different ways: through monthly studio membership, which provides artists access to printing presses and equipment; exhibition opportunities with our workshop gallery: classes for experienced and first-time print makers; and a visiting artist program for local and nationally-know artists.

LEO:why did you feel calliope Arts is needed in Louisville?

Sc: print marking studios like Callipe arts are location all across the country. Because Louisville's  arts scene is steadily expanding, along with the metro area's local university art programs, it's especially necessary for artists to be able to fine a space and a community to work in after school or when they're trying to make a living to support their practice. calliope's workshop gallery exhibits fine art lithographs, woodcuts Screen Prints and etchings from renowned and great entry point to collecting artwork. we look forward to opportunities to help Louisville area residents learn more about printmarking processes, print's role in contemporary art and collecting original art to share with their friends and families.

LEO: Since part of the Space is dedicated as a gallery, when do you plan to start showing Exhibition?

SC: our workshop gallery is currently displaying framed and unframed work from artists working in Studios and universities in France, California and Massachusetts. Our Frist visiting artist, Douglas Daggers, a recent Millay colony and Vermonter Studio center resident, is coming oct 13-20 to make artwork, which we will also have on display curated, themed Exhibition are something that wll started happening in the next year or so, in which we put out Specific calls for entry.

Leo: As individual artists, what type of printmaking do you prefer to do?

SC: I have been making work in Cyanotype, which is essentially a photographic blueprint process. i make work about the lost or forgotten histories of specific places, so i like to use the socially-charged history and visual language of printmaking to enrich my research-based projects. Rudy is looking into using a pneumatic engraver for his next project, Which basically a 21st-century take on a 15th-century tool. We're both looking forward to working with local maker spaces to make wood blocks and plates with laser cutters and CNC routers. 

LEO: since you are print-makers who are married, tell us a little about your life stories.How did you meet

SC: Rudy and I met at the university of low a in 2009 where we received our master's degrees in printmaking. this means that throughout our relationship, we've always been very busy and working together towards specific goals for our art, life and work. We were both frustrated that our students often stopped making prints after graduation, because it's so difficult to buy and house prints making presses and equipment and nothing really beats the collaborative atmosphere of a shared printing work space. We moved to Louisville in 2012 to start calliope Arts, Which Would Provide a Space for emerging artists to make work alongside professionals, which is something that meant a lot to us in both of our past experiences after college. We got married in October 2013, so our two-year anniversary is just around the corner, which is also about the anniversary of the time that we've spent working in the space that is now calliope Arts.Running a business together has been intense and wonderful so far, because we have such different skills and interests. Rudy's parents run a dental lab in southern California, so he grew up in a live/work environment, with the lab on the same lot as his childhood home. he's great at managing time and planning very complex processes like sourcing and receiving work for exhibitions, and i,m better at marketing, designing our classes and graphic design. someday we may have help with some of these things, but i think we both got into art marking because we love to do many very different types of work, and our approach to art brings so many experiences into our lives.

when architects at architecture incorporated next present a plan for campus development to a potential client, they will bring a model created by a 3-D printer.

For now, its sits on a conference table at the downtown sioux falls firm firm-a replica of a large piece of land with miniature three-dimensional buildings designed by the architects.

"instead of spending hours and having to build it by hand... those were done in about two days of throwing it on the printer, "architect catherine Dekkenga said.

nearby, another model is "more of a dream," she said. it shows the firm's own building at 415s. Main AVe.and how a nearby parking lot might be redeveloped.

The 3-D printed model allow a architects to pop up the parking lot's footprint and see how other buildings might look there.

"the idea is what can we put in between there instead of just a parking lots, " Dekkenga said. "what would a skyscraper look at them.

"It's hard because it is an expense, and sometimes smaller firm haven't invested yet but there are tools like this that definitely architects are starting to use a lot more," Dekkenga said.

Architects historically have embraced new technology as a method to help clients understand designs before anything is built, said Dave van Nieuwenhuyzen, director of architecture at fiegen construction Co. and president of the south Dakota chapter of the Americna institute Of Architechts.

"computer programs have come a long way as a tool in accurately producing renderings, images and animation.. and placing them into the context of the site or in the case of an addition or remodel into the existing conditions,"he said.

"Now, with the advent of 3-D printers and other virtual reality technology, architects are able to produce more and better with these new tools. talking 2-D prints into the 3-D environment helps the client see their project come to life."\

At Architecture Incorported,. "we've always had a commitment to try  to do the new stuff, at least try it out,"founder and president Dick Dempster said. "I love It. I'm of the era where we cut our fingers with X-Acto knife Blades... and now you create those shapes on the computer and just print them out. It,s Exciting."

The firm will get even techier soon when it starts using Oculus Rift, a virtual reality system that uses a headset to immerse someone in a scene.

"you put on the glasses, and you can hook up a joystick and walk through the space-upstairs, through doors, down a hallway and experience the whole model," Dekkenga said.

The architects tried it out following a trade show recently and were hooked.

"It was almost like a roller coaster," Dekkenga said, as she tried it out with design of a church i got to walk on the balcony, down some side stairs, through doors and into a hallway," she said. "It was neat. This is a whole new element of feeling the space and being surrounded by it."

The new technology will be a unique perspective for clients. Dempster said, but he's also excited about using it to better communication with engineers and for his staff to visualize project as they are working on them.

"I'm anxious to see how it works when we walk through a campus setting, an assembly of buildings or a downtown area," he said.

"it will be a great tool for integrated into higher education before they are introduced in professional offices, he added.

That's also the case at south Dakota state university, where architure student use multiple 3-D Printers in their designs as well as cnc router to cut models.

there's also a plasma cutter to cut steel and a 3-D laser scanner, which students can use instead of measuring and drawing spaces.

Department chairman Brian Rex Compares the technology to "like you see in CSI where you put it in a room aor space... and it sends out a pulse of laser, and when it bouncess back, it does all the point in space around it."

the school is trying to develop new architechts with knowledge of technology who can help firm move forward, he said.

"All these change that used to be kind of radical ideas are fairly standard when you have people who know how to use them,"Rex said. " they're no longer the extravagances they once were, and clients paid for it though the nose. Now, every client expects it."

Addining new technology also will help Sioux Falls compete with Firms From other markets that are eyeing the city for business, he said, while adding that firms in the whole area "are doing a really good job"

"There are no cities this size I Know of that have this many firms that are this good."

Creating Organic wood textures with a laser machine.

we Live in a time where technology is growing at exponential speeds. At a recent woodworking show, I stumbled across the idea of laser technology and furniture for a simple low-cost way of creating texture. the laser has been used in laboratories since the 1960s and continues to amaze the mind with new unique application as the decades go by.

Laser Printing on Wood

Rather than using a traditional ink printer, a laser machine uses the power of the laser to precisely burn or engrave depth into a material. the process starts by capturing a digital photo of the surface material you want to replicate. A simple picture taken with any smartphone device will have more than enough resolution to easily store a quality high-resolution image.if you are not a photographer than a quick search on internet will locate hundreds of patterns, textures and wood grain prints.

High-speed laser engraving on fiberboard

A remarkable material for this laser engraving process is medium density fiberboard(MDF). The surface of MDF is flat, smooth, dense and free of knots and grain patterns. The Homogeneous density profile of MDF allows intricate and precise laser machining and finishing. This material is widely used in the manufacture of furniture, kitchen cabinets, signage, store fixtures, paneling, and other mill work applications. MDF is the perfect solid wood substitute. The stability, Strength, and cost allow for an increasing number of applications.

Many MDF panels today are using computer numerical control (CNC) router technology to produce complex grametry and patterns on the surface. Kern laser system is combining software and co2 laser to produce realistic wood grain depths and patterns. Their large format laser engravers use a high-speed scanning head to laser engrave a true 3D surface texture depth. it's possible to supply an endless library of images into the machine. MDF panels can be specifically laser machined as an effective alternative to solid wood components. they can be used in place of expensive, hard-to-source exotic woods.

Another growing technology today includes 3D printers as a way of manufacturing almost any model or prototype. Through plastics Powder or Filament spools, you will be able to create your product from the ground up.Although this is a fascinating field,the production of wood panels and other surfaces would take an extremely long time to Manufacture. High-speed laser engraving on a manufactured substrate like MDF will produce a much higher volume and a much larger panel size.

Head Case : Jorge Pardo creates a hall of mirrors at david gill gallery
At first glance, Jorge Pardo's huge oval-shaped mirrors that are currently lining

the wall of london's David Gill Gallery look as if htey are framed by abstract flowers made up of concentric circles. however on closer inspection, the outline of each swirling pattern can be identified as the cross section of a skull.

cut on a cnc router, the cerebral head scans each belong to a writer or thinker admired by the Havana-born artist. Among the anonymous portraits are Hal Foster, Hans-Ulrich Obrist, Food writer Jonathan Gold and the great art critic of the modernist era, Clement Green berg.

A series of cabinets and tables featuring portraits of the artist and his family are displayed alongside the mirrors. I thought it would be interesting if this show took on the role of a convoluted portraiture machine with all the works having different forms of portraits, 'say Pardo. 'The mirrors are portraits of critics, the furniture with Portraiture of my family and the tables will have images of me. some of the furniture will also hang from the wall like paintings.'

The 12 mirrors, each measuring 274cm in height, feature a constellation of 12 heads that amplify the natural irregularities in the shape of the skull. the patterns are random, 'says pardo. 'when i work with patterns and colour my interest is density of irregularity. It's a simple system, which is really not much of a system: I choose a shape to diperse colour and any combinations of colour work'

Greasing Your CNC Cutting System

We’re always talking about how to maximize the longevity of your CNC machine and consumables. Proper and timely maintenance is of course the easiest way to ensure you’re getting the biggest bang for your buck. Just as you would change the oil in your car or use WD40 on a squeaky door, adding grease to your CNC machine ensures it runs smoothly.

We recommend re-greasing your machine every month. There are 3 main areas for greasing: the bearing cars, the racks, and the ball screw (in most CNC models).

Bearing cars

Bearing cars can be found on either side of the x-axis gantry, y-axis, and z-axis. Using your grease gun, position the tip directly over the small ball inside the bearing car. Make sure you are compressing the ball. For a properly primed grease gun about 3 squeezes should do it. Wipe off any excess grease and repeat for all bearings.

On some older CNC machines the ball will not be directly accessible for the grease gun. Use the smaller attachable tips to compress the ball, and squeeze the grease inside.

Racks

 A light coat of grease is recommended for all of the racks. Lightly squeeze your grease gun as you move along the racks. Then use you finger to ensure the grease has gotten inside the teeth of the racks, as well as removing any excess grease. Remember only  a light coating of grease is needed; too much will just cause a mess and trap dirt and debris.

 Ball-Screw

On most MultiCam models, a ball screw is used to move the Z-axis up and down. Same as the racks, use just a small amount of grease around the screw. Usually just using your finger is sufficient. Again, if you use too much grease you will be trapping too much dirt, which can be especially problematic around the ball-screw. You don’t want chips or debris flowing down the ball-screw as this can damage the ball nut. For our V-Series models, there isn’t a ball-screw. Instead there is another rack and pinion so you can follow the instructions above.

After 6 months we recommend a complete grease clean-up. Using a de-greasing agent, de-grease all bearing cars and racks, and then re-grease them. Why go through all this trouble? Grease is a lubricant but it also traps dirt and debris, which can eventually lead to build ups. Too often we get calls from customers about poor cut quality or cut chatter and the reason stemmed from a build-up of dirt. Save yourself a potentially expensive service call by instituting a semi-annual clean-up.
For the ball-screws however, do not use a de-greasing agent. Instead use another lubricant, like a torch lubricant in a plasma system. Lubricate the ball screw and then wipe everything clean with water, then re-apply the grease. We say this because it’s extremely important that chips and debris do not travel down into the ball nut. A de-greasing agent can do it’s job too well and debris will slip down into the ball nut. Dirt in the ball nut can cause binding which eventually results in a motor fault. If debris is stuck in the ball nut, the motor needs to work harder to move the Z-axis, drawing too much amperage, thus causing a fault.

We sell grease cartridge packages and grease guns. Just visit store.multicam.com and order yours today! Save yourself the hassle and expense of machine down time by just sticking to a proper greasing maintenance schedule.

Emily Hermant, who joined the faculty this semester as a assistant professor of sculpture, seeks to inspire students in the sculpture foundry in the woldenberg art center on the Tulane University uptown campus.New Digital art were a gift from new Orleans resident louis jung, in honor of this mother, harriett Tolar Jung, a 1940 Newcomb collage graduate who majored in painting.

Artist Emily Hermant’s practice often plays with aspects of permeating technology in contemporary life. Her work reinvents the ancient art of sculpture using modern materials.

Hermant, whose practice spans sculpture, installation, fibers, digital media and drawing, joined Tulane University in August as an assistant professor of sculpture in the Newcomb Art Department, housed within the School of Liberal Arts.

“It’s exciting to be at Tulane to develop a sculpture program that incorporates nontraditional approaches,” she says. “It’s an opportunity to expand the repertoire to include practices that have historically existed on the margins of the field.”

Receiving critical acclaim, Hermant’s beautiful, thought-provoking work has been exhibited internationally. The Washington Post described Hermant’s Spatial Drawings, in which long planks of wood have been curved into graceful and unusual poses, as “wavelike ribbons of lumber … as lithe and leanly muscled as ballet dancers … [her] sculptures activate the space they’re in, along with our perception of it.”

Hermant, who hails from Canada and received her MFA from the School of the Art Institute of Chicago, says that she “will encourage students to experiment and take risks, to work in new ways with traditional materials, to develop ways of using new materials, and to experiment with emerging technologies.”

Hermant as well as other Tulane artists can experiment with new sculptural work and test their boundaries using the Newcomb Art Department’s CNC router, a computer controlled cutting machine, and 3-D printers. With a CNC router, an artist designs artwork in a computer program, and the computer communicates to the machine how to carve the artwork. A 3-D printer works in a similar fashion, but by methodically adding material.

These digital art tools were a gift from New Orleans resident Louis Jung, in honor of his mother, Harriett Tolar Jung, a 1940 Newcomb College graduate who majored in painting.
