A force model was developed for crankshaft pin grinding to predict the forces generated during grinding. The force model developed builds on the authors' previously developed model, which predicted the outofroundness in crankshaft pin grinding. The model includes key grinding variables, such as the work removal parameter (WRP), system sti€ ness and Youngrsquo;s modulus to determine the ...

Designed to use varying degrees of impact and agitation to process materials, the Sturtevant Simpactors ® are among the most versatile equipment available in the materials processing industry.
