/心形凸台零件的数控铣削加工工艺及其编程【摘要】本文主要介绍了心形凸台零件的数控铣削加工工艺及其编程，开篇首先介绍了数控技术的概述并对数控技术原理加以解释，紧接着对零件图进行了简要的分析并确定其加工方式，然后确定零件的毛坯、定位基准、装夹方式、刀具、量具、切削用量等等，再制定出合理的加工方案，并制定相关的工艺文件，最后编制出零件的加工程序，在编制程序时运用了自动编程与手工编程相结合的方法编制，自动编程的应用大大减少了编程时的计算量，同时也使得程序更加准确无误。本文对本公司一项心形凸台产品阐述加工中心对其复杂形状的工件加工，主要分析了心形凸台零件的结构特点、加工要求、制定加工工艺、选择刀具夹具以及确定切削用量等。利用数控车床高精度的特性，对于高精度要求再适合不过。对于高精度要求的加工，位置误差的把握。在加工中零件对尺寸的高要求，自己对数控车床使用也越发熟悉。我信任自己一定能独立的完成一项加工。【关键词】：数控编程；工艺分析；切削用量；加工方案；目 录绪论错误！未定义书签。一、零件的图样分析3（一）零件的结构特点分析··········································································3（二）零件的技术要求分析··········································································3二、零件的工艺规程设计3（一）毛坯的选择······················································································3（二）定位基准的选择················································································3（三）装夹方式的选择················································································3（四）表面加工方法的选择··········································································3（五...
