3D CNC Manual For CAD/CAM (Or Computer Numerical Control 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
moulder and the boring machine. They can also cut mortises and
tenons.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.
