In this paper a non contact measuring system for free form surfaces is proposed based on coordinate measuring machine,PH10 probe head and laser triangulation probe.

The result of experiment indicates that the system has high precision and credibility, and it is easy to operate, it can meet the automatic alignment demand of revolving parts.

This paper introduces the structure and the function of the die CAD system for the revolving parts based on 3D platform of Solid Edge.

The mechanism of feature-based process reasoning for the extrusion of revolving parts was researched based on the forming characteristic of revolving parts.
