• 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 specific

May 20, 2014 Solution # 3: Increase Spark-Outs. Spark-outs are a period of time where the wheel is oscillating but not feeding– typically consuming 2-5 seconds at the end of a 20-second bore grinding operation. So spark-outs can occupy up to 25% of the machine cycle. Some manufacturers cast a greedy eye upon those 2-5 seconds, thinking of them as useless
