CNC machine can be divided into two categories: the nc lathe and nc milling machine. Numerical control lathe usually consists of clamping workpiece high-speed rotating device and a can cut to workpiece excess material tool composition (tool can be in workpiece up to and from sports, until get the desired shape of the). Nc milling machine is a kind of can in the X, Y, Z axis three directions of milling processing device. the nc lathe and nc milling machine does not necessarily need computer to produce a queue to control. Numerical control technology and computer technologies can allow people to first of all on the computer design products, and then define how nc machine tool processing the product. Product design is on the computer generates a computer aided design documents, then need people define how NC machine tool processing the products and, in the end, it step produced a computer aided manufacturing file (or G code files, or NC file, this type of file have many name). The computer aided processing file contains all of the nc machine tools must follow the steps machining information. Computer and CNC numerical control machine tool communications tell it how to explain these processing document to carry on the processing. Nc machine tool by: procedures, input/output device, CNC unit, servo system, position feedback system, machine body composition. 1. program storage medium, also called program carrier 1) Punched tape (outdated, e
