ABSTRACT
CNC milling machine (Center) is Machining processing Center in general milling machine developed on the basis of the Machining process, both basic and same, structure, but also some C milling machine is on the process of automatically controlled machine tools, so its structure and have very big distinction.
CNC milling machine (Center) Machining processing Center, is as MC mechanical equipment and control system for the efficiency automation ponents. It is efficient machine, CNC, precision workpiece in time in the clamping can finish a number of processes, CNC machining center is processed in the nc machine plicated structure and function of a machine. Suitable for plex shape, processing content more, demanding, need many types mon tools and many of the technology and equipment, and by many clamping and adjust to finish machining parts.
Usually the workpiece machining processing center, both plane and the pore structure parts, complex shape, ordinary machine parts processing, appearance is shaped parts, the periodicity of irregular parts processing, production of high precision and small batch production parts ponents, and its processing is widely content.
CNC programming are generally classified into manual programming and automatic programming.
Manual programming is analyzed, and determine from p
