Feeds and Speeds Charts

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
