2、工中心的编程与操作,是在学完了数控机床及其应用和相关的大部分专业课,在计算机上进行模拟与仿真.在生产实习的基础上进行学习的一个重要教学环节.通过本题设计,提到数控加工中心的原理.零件编程所用的指令,并解释,加工的零件各部分尺寸精度和表面质量均达到零件的要求.在数控加工工艺设计中包括(零件图的工艺分析,毛坯的选择，工序划分,切削用量,走刀路线等).通过设计,我对数控加工中心的整个加工过程有了较全面的理解,经过在设计中选择刀具,我对数控铣床系统的特点与指令,刀具材料和使用的范围有了较深的理解,基本掌握了机床刀具的选用方法.经过编制零件的，基本熟悉了数控编程的主要内容及步骤,编程的种类,程序的结构与
3、格式.另外还学会了在计算机上进行模拟，虽然课程设计比较复杂,但在设计过程中不断学习,在工艺方案确定后,加工程序也经过多次修改.最终完成了零件的加工由于能力有限,经验不足,数控技术发展迅速,设计中还有许多不足之处,希望各位老师多加指教,提出宝贵的意见.关键词：关键词：数控加工中心，编程，工序划分，加工程序，尺寸精度，数控技术发展。AbstractAbstractThis time carries on the numerical control processing center in the graduation project the programming AND-OPERATION, w
