加工中心训练图纸高级

1、训练题目：复合零件的加工一、图样与技术要求 零件立体图零件图训练要点：1.能够编制平面铣削程序2.能够编制含直线插补、圆弧插补二维轮廓的加工程序3.能够宏程序编制椭圆程序二、工艺规程设计1 刀具及切削参数选择选择合理的刀具加工参数，对于金属切削加工能取到事半功倍的效果。根据加工对象的材质，刀具的材质和规格，从金属切削参数书籍中查找刀具线速度、单刃切削量，确定选用刀具的转速、进给速度，参考切削参数如表11：表11刀具切削速度v （mm/min）每刃进给量f（mm/刃）主轴转速S（r/min）进给速度F（mm/min）备注ø 12mm立铣刀600.051600200粗加工ø8m
