Process analysis of bushing parts

(1) Part material: 45 steel. The machining is good.

(2) Part composition surface: outer round surface (-50, 35, 33), inner surface (-31.5, 20.5), type hole, two ends, inside and outside step face, inside and outside exit groove, inner and outer chamfer.

(3) Main surface analysis: the inner hole of 20.5 is not only the support surface of the other parts, but also the main basis of the part;
