Papers by Keyword: Specific Grinding Force

Abstract: In the grinding process, due to the elastic deformations of grinding machine and grinding wheel, the ground depth of cut is smaller than the applied depth of cut. Consequently, the ground depth of cut has to be controlled in spark-out grinding process. However, the cycle time in spark-out grinding process is not easy to be estimated. From such a viewpoint, in this study, using specific grinding force obtained by measured grinding force in the first spark-out pass, a calculating method of the real ground depth in continuous pass process is proposed. And, this method is experimentally evaluated.

Abstract: An investigation is reported on high-speed single-grain grinding for superalloy. The grooves’ morphology and area removal ratio, grinding force ratio, specific grinding force, and friction coefficient are studied. The area removal rate η increases with the grinding section area increasing. The plowing decreases with the grinding section area and grinding speed increase. Surface integrity can be improved under high speed and deep grinding. It is proved by experiments that the single-grain grinding friction coefficient decreases with the grinding speed increasing.
