Our factory has encountered the processing of the small-diameter cylinder shown in Figure 1. The cylinder length is 700mm, the inner hole is φ42_0~(+0.12)mm, the material is 45 steel, the inner hole surface roughness R_a1.6, the hardness is 220-260HB. Because the boring head and the honing head of our factory do not have such specifications, the processing tasks are urgent. To this end, in order to ensure the pattern requirements, we use the end mill instead of the reamer to finish the inner hole. Before the machining, the end mill is subjected to the geometric angle sharpening correction.
