What is Cutting Speed Feed Depth Of Cut in Machine tools

The depth of cut is the distance that the tool bit moves into the work usually measured in thousandths of an inch or millimeters General machine practice is to use a depth of cut up to five times the rate of feed such as rough cutting stainless steel using a feed of 0.020 inches per revolution and a depth of cut of 0.100 inch which would reduce the diameter by 0.200 inch.
