Cutter radius compensation(CRC) is a very important function of numerical control(NC) system.We refer to a large number of NC information and sum up the CRC function.We illustrate how to realize rough machining & finish machining by the same program,machining matching surface by the same program,simplify programming methods,realize direct programming by parts contour,remove machining allowance by the increase of CRC value,control the parts size precision by adjusting the CRC value,state the essence of the CRC,and elucidate the physical meaning of the CRC value.
