The Proposed model has the merits of reflecting the various aspects of ring rolling process more accurately and making it possible to realize the CAD/CAM system in practical ring rolling production.

结果表明，该方法能较精确地反映出环件轧制中各物理量变化规律。因此，为实现环件轧制过程的CAD／CAM奠定了基础。

The tracer CAM of piston ring is designed according to the principle and method proposed in this paper and the computer simulation result of this compensation effect is given.

按照上述原理设计了活塞环仿形靠模，并对其补偿效果作了数字仿真。
