2 Increase the cutting speed feed rate until the quality of the part s finish starts to decrease or the part is starting to move from hold downs Then decrease speed by 10% 3 Decrease RPM until finish deteriorates then bring RPM back up until finish is acceptable 4 This optimizes RPM and speed to remove the largest possible chips

Millstone Wikipedia

In some sandstones Especially in the case of wind powered mills the turning speed can be irregular Higher speed means more grain is fed to the stones by the feed shoe and grain exits the stones more quickly because of their faster turning speed The miller has to reduce the gap between the stones so more weight of the runner presses down on the grain and the grinding action is increased
