A cycle time is a measure of how long it takes to produce a given part. For example, a part may take 20min to run 10 parts. The cycle time is then described as 2 min per part.
CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.

Set up time Time for setting and fixing the job and tool. It also include time
It can be seen from Figure 8 that the cycle time decreased very quickly with infeedrate with k = 1. The cycle time for the first workpiece took an unusually long time of 74 seconds probably due to this being the first workpiece to be ground after changing the grinding wheel. CBN wheels often have a poor grinding efficiency just after dressing.

Production Time Calculator. The production time for a manufacturing process is primarily determined from the cycle time, but must also account for the defect rate, machine uptime, and machines used. Using these parameters, the run quantity, run time, down time, total production time, and production rate (parts/hr) will be calculated.
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 ...
