CNC milling machine (Center) Machining processing Center, is as MC mechanical equipment and control system for the efficiency automation machine 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 more plicated structure and function of a machine. Suitable for processing plex shape, processing content more, demanding, need many types of 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, plex shape, ordinary machine parts processing, appearance is shaped parts, the periodicity of irregular parts processing, production of high precision and small batch production parts and 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 parts processing, the numerical calculation, the writing parts processing procedure and program control medium to check is artificially. CNC machine safety operation: the CNC safety procedures and matters needing attention, machine parts of the button switches and handwheel function and, as well as the function and effect of the machine tool, the operation of the panel used maintenance. This design is mainly about the emergence and development of numerical control equipment, CNC processing principle, characteristic and application of nc machining and manual programming knowledge. Keywords: CNC。 本次設(shè)計(jì)內(nèi)容介紹了數(shù)控加工的特點(diǎn)、加工工藝分析以及數(shù)控編程的一般步驟。在全球倡導(dǎo)綠色制造的大環(huán)境下,機(jī)床數(shù)控化改造成為了熱點(diǎn)。現(xiàn)代的
