我们在试制装配汽车用的风动扳手时,其中行星齿轮架上的螺旋形人字槽(图1)的加工很困难,为解决这一难题,我们采用了直角座标法进行铣削加工。将工件装夹于分度头上,在旋转分度头的同时,使X62W铣床工作台作纵向走刀,用这种方法终于将人字槽铣成了。 但是,过去由于分度头的旋转运 When we were trying to manufacture a pneumatic wrench for assembling a car, the helical groove on the planet carrier (Figure 1) was difficult to process. To solve this problem, we used the Cartesian coordinate method for milling. The workpiece is clamped in the indexing head, turning the indexing head at the same time, make the X62W milling machine table for longitudinal cutting, in this way, finally the humanoid groove milling into. However, due to the rotation of the index head
