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.

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.
