Closer to international standards, technical standards, standardization work has been a new development, thus greatly improving the mechanical design and product level. CNC machining precision aim is to enable more efficient, reduce human processing errors. In order to meet and adapt to this new situation. Therefore, I outlined a typical shaft parts processing technology and processing program, have learned through their own professional knowledge and practical experience and processing of CNC machine tools and general machine tools to a reasonable bination of better applied to in practice. For enterprises, the product quality is the basis for enterprises to survi ve, then the product process is the fundamental rationale of the fundamental. I through process planning, machine tools and CNC machine tools will be ordinary and reasonable bination, so that the rationalization of existing resources, to achieve lowcost, highyield, first of all to determine the shaft processing program, and then select the map set size to meet the requirements of machine tools, to determine the processing process. The main contents of Graduation Design CNC machining shaft parts process design. Using ordinary machining and CNC machining a bination of design preparation shaft parts of the general process planning and CNC machining process planning, and preparation of finishing CNC machining process. The reducer output shaft for the processing and use of CNC lathes C616A processing, using wire cutting technology to cut a good heattreated rough, and then lathe to rough, firstaxis face a good car, leaving a certain margin of speed up the shaft 2 to the outer end chamfer. Then right Keyway milling cutter with the semifinishing, and finally C616A CNC lathe to finish grinding to ensure bright face of the parallelism deviation is less than , the size of cylindrical ensure φ68. Let each part of size are up to par. key words： Machining CNC Machining Process 四川科技職業(yè)學(xué)院 畢業(yè)設(shè)計(jì) (論文 ) 第 VI 頁(yè) 目 錄 第一章 緒論 ........................................................................................................
