If you are looking to improve your CNC milling it is essential to optimize the depth of cut and the stepover. The depth of cut is essentially the length of the side of the flutes that are doing the cutting. It is the thickness of the current layer that you’re cutting. The stepover which is also known as the cut width is the thickness of the cut when you are looking at it from above. Cutting speed is also known as your spindle speed.
- The depth of cut is the length of the side the flutes are cutting, so really this deals with thickness of the current layer.
- The cut width is also called a stepover and is the total thickness of the cut when you look from above.
- The material removal rate deals with the shape of the tool, the depth of cut, the stepover and the feed rate.
“For the sake of completeness, Cutting Speed is defined as your spindle speed (in rpm) in the cut.”
