The Cycle Time Formula is an essential manufacturing KPI to understand in manufacturing. It is used by ERP and MES systems for scheduling, purchasing and production costing. It is also a critical part of the OEE calculation (use our OEE calculator here).Fortunately, it is easy to calculate and understand.

In grinding operation, elastic deformations of the grinding machine and the grinding wheel induce a residual stock removal of workpiece. On the other hand, thermal expansions of the workpiece and the grinding wheel increase the depth of cut. Therefore, calculation of a ground depth of cut and/or the grinding time has to be considered by the elastic deformations and the thermal expansions.
