About CIM – CNC Milling Machine

CNC Milling Machinery

CNC Milling is a technology whereby the rotating milling cutter of a milling machine tool is driven by a computer to produce a desired shape. The Numerical Control computer is programmed to drive the motors attached to each of the machines moving axes in a discrete manner to create the cutting action, which will produce the desired shape in a work piece. Electronic measuring devices are attached to each moving axis and monitored by the CNC to assure accurate movement according to the program. These can be either a direct measuring device eg; linear encoder or scale or indirect measuring device eg. rotary (pulse) encoder or even a resolver.

In this way a CNC machine can produce the same part as a human operator much faster and with greater precision.
