Abstract: Virtual camshaft part is a very important information carrier for camshaft virtual high-speed grinding. The veracity and maturity of process correlation information, which holding on the virtual camshaft part, will directly determine the virtual high-speed grinding results’ authenticity and practicability. By analyzing geometrical structure and all kinds of process correlation attribute information, a method of process information parameterization of camshaft part for virtual high-speed grinding was presented in this paper, and a practicable function module of camshaft virtual part parameterization define was developed according with this mind.

Abstract: Camshaft is one of the key components of vehicle engines. In this paper, an independent optimization and simulation module for camshaft grinding was developed. First an optimization algorithm based on the least square method was proposed according to the constant linear velocity mathematical model of the camshaft. The algorithm can be used to smooth speed curves and improve machining efficiency and accuracy. Then the real time dynamic simulation of the camshaft grinding process was finished to perform the machining status according to the optimized motion path of the process system components.
