补充资料：平面刨削方法
刨削方法必须针对不同表面加以制定，而且不同的表面应用不同刨刀才能加工。
刨刀常用的有平面刨刀、偏刀、角度偏刀、切刀、成形刨刀等几种。按所刨平面倾斜方向不同，又可将偏刀分为左、右偏刀。
一、刨水平面
水平面既可以是零件所需要的加工表面，又可以用作精加工基准面。
水平面粗刨采用平面刨刀，精刨采用圆头精刨刀。刨削用量一般为：刨削深度ap为0.2～0.5mm，进给量f为0.33～0.66mm/str，切削速度v为15～50m/min。粗刨时刨削深度和进给量可取大值，切削速度取低值；精刨时切削速度取高值，切削深度和进给量取小值。
对于两个相对平面有平行度要求，两相邻平面有垂直度要求的矩形工件。设矩形四个平在按逆时针方向分别为1、2、3、4面。一般刨削方法是先刨出一个较大的平面1为基准面，然后将该基准面贴紧平口钳钳口一面，用圆棒或斜垫夹人基准面对面的钳口中，刨削第2 个平面，再刨削第2 个平面相对的第4个面，最后刨削第1个面相对的第3个面。
