normal style="TEXT-INDENT: 17.95pt">（1）零件图工艺分析
normal style="TEXT-INDENT: 17.95pt">为便于定位装夹，Φ100f9外圆、80尺寸两面、78尺寸上面均在前面工序中用普通机床完成。数控加工的主要内容是：2-Φ15H7孔，Φ35H7孔、Φ60×12窝，2-Φ11×Φ17、2-M6-6H螺孔。
normal style="TEXT-INDENT: 17.95pt">（2）选择设备
normal style="TEXT-INDENT: 21pt">根据被加工零件的外形和材料等条件，选用的卧式加工中心，其主要参数是：
normal style="TEXT-INDENT: 21pt">工作台尺寸：400㎜×Φ400㎜、工作台左右行程（X轴）500㎜、工作台前后行程（Z轴）400㎜，主轴箱上下行程（Y轴）400㎜，主轴中心线至工作台面距离100～500㎜，主轴端面至工作台中心线距离150～500㎜，主轴锥孔BT-40，刀库容量30把。
normal style="TEXT-INDENT: 17.95pt">（3）确定零件的定位基准和装夹方式
normal style="TEXT-INDENT: 21.2pt">工件以Φ100f9外圆、80尺寸左端面定位。
normal style="TEXT-INDENT: 17.95pt">（4）工件坐标系设定
normal style="TEXT-INDENT: 17.95pt">B00、G54、X0、Y0设在Φ35H7孔中心上，Z0设在80尺寸左面。
normal style="TEXT-INDENT: 21pt">B900、G55、X0设在80尺寸左面。Y0设在Φ35H7孔中心上，Z0设在78尺寸上面。
normal style="TEXT-INDENT: 21pt">（5）确定加工顺序及进给路线（分析略）
normal style="TEXT-INDENT: 21pt">（6）刀具选择
normal style="TEXT-INDENT: 21pt">将所选定的刀具参数填入表1支承套数控加工刀具卡片中。
