The great grinding divide | Cutting Tool Engineering

An even simpler formula that's used in calculations in just about every grinding process is the specific material-removal rate, Q', known as "Q-prime." Q' = a e × v w where a e is the DOC measured in mm and v w is the feed rate measured in mm/sec. The specific mrr is the total mrr per unit width of the grinding wheel.

Estimation of Grinding Cycle Time Taking into Account ...

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 …
