In other words, Chip Load is the thickness of the material that each tooth removes per each revolution. It is commonly expressed in Surface Feet per Minute (SFM) or Surface Meters per Minute (SMM).Ĭhip Load is the advancement of each tooth per revolution of the tool. The combination of these two factors determines your initial Cutting Speed and Chip Load that you can put into the speed and feed formulas to calculate the cutting tool RPM and feed rate.Ĭutting Speed is the speed at which the tip of the tool travels through the material. It starts with knowing what workpiece material you have and what tooling and how you will be using to machine it. One of the primary tasks machinists must learn to perform is a calculation of speeds and feeds required for milling, drilling, and turning.
