Computer Numerical Control (CNC) points out how workers, operators, and engineers’ control and operate production equipment using a computer program. These devices use a coded language known as ‘g-code,’ which commands the machine on how to mold, cut, grind, shape, or melt different materials like metal, wood, or plastic. There is a wide variety of CNC machines in the market, but the most commonly used types are:
The CNC milling machines are also popularly known as multitasking machines. The function of the milling machine is the turning and milling of materials. It has a fixed cutter that aids in the detachment of materials from the surface of the workpiece. The milling machine manufactures high precision parts into different components and shapes.
The Lathe is the device that rotates the material on a spindle. Between the revolving process, the content is compressed by the grinding or carving tool that slits it into the desired shape. The lathe machine is mostly used to lacerate symmetrical objects like spheres, cones, and cylinders.
The CNC technology operates the most commonly used machinery, the CNC Router. This machine is entirely run by the computer, there is no need of any human interference. The largest dimensions of wood, metal sheets, and plastics are produced by these Routers. Its unique design allows cutting in three-dimensions. The advanced routers are being fabricated with 4, 5, or even 6-axis that manufactures and manipulates prototype models and complex shapes.
Both in size and structure, the plasma cutters are very similar to the routers. They are designed to slit two-dimensional profile shapes into sheet metals with a powerful plasma torch.
The laser cutter deals with the same principle as the plasma cutter. The only difference between both the cutters is in the laser cutter powerful laser is used instead of the torch. CNC machining parts provides both efficient parts.
The 3D printer has the same functioning as the router and laser cutter. But the 3D printer is an additive machine and not subtracting.
