Part Constructability Analysis

The main problems solved in the analysis of the processability of the part design are reduced by the possible reduction of labor intensity and metal consumption, the possibility of processing the part with high-performance methods. Thus, improving the processability of the part design allows to reduce the cost of its production without compromising the service purpose.

A fairly low technological element is a toothed rim, which takes more time to process. The toothed rim can be machined on a toothshield, with the required degree of accuracy being achieved, and gearing or gearing is required to achieve roughness of the dividing Ø Ra 1.25.

Processing of Ø80H7 requires double turning and grinding.

For the treatment of holes Ø6, a large drill run and at the same time it is possible to remove it.

In general, having studied the design of the part, it can be considered non-technological.
