- calculate cycle time in surface grinding
Less time is required for the dressing cycle. ... Using the correct wheel angles helps to ensure that the entire surface of the grinding wheel is in use. If the angle of the regulating wheel is too acute, it can cause the workpiece to go too far into the grinding zone. This can result in uneven wear, tapering, and reduced wheel life.

Balance and run-out of the grinding wheel are mechanical properties that must be addressed at the time of each grinding wheel mounting. Regardless of the overall rigidity of the machine, surface finish and grinding performance will not be maximized if the grinding wheel is not running true and is not dynamically balanced.

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.
