通常从圆形坯料上车削环状物时包含两道工序 ,即先钻出与环内径相等的孔 ,再用切断刀一个个切下 ,这样就有许多工作量并且浪费材料。这里有一种设想 (如图所示 ) ,首先在外圆表面车出槽形 ,其槽深略大于环的壁厚 ,槽的间隔等于环的轴向厚度 ,然后用车刀从圆柱体的端部切入即可 In general, the process of turning a ring from a circular blank includes two operations, that is, drilling an aperture equal to the inner diameter of the ring and then cutting the cutters one by one, thus requiring a lot of work and wasting material. There is an assumption (as shown) that first the car is driven out of the groove on the outer surface of the groove, the groove is slightly larger than the wall thickness of the ring, the groove spacing equal to the axial thickness of the ring, and then with a turning tool from the end of the cylinder Cut into the can
