Left bearing seat parts and rough drawings of how to draw?

Answer:

One method is to mark the machining allowance on the machined surface on the basis of the part drawing, and to increase the technical requirements relating to the blank parts;Another method is modeled on the part drawing, but not the dimensioning and symbol processing after processing, dimensions and tolerances of the blank, the relevant requirements of the relevant technical requirements into the blank (such as surface roughness, draft and casting casting defects etc.). But it should be noted that the size tolerance grade of casting parts is self-contained.
