In computer-aided manufacturing (CAM) and CNC milling, the Feed Rate ( ) is the linear speed at which the cutting tool moves through the workpiece material.
In computer-aided manufacturing (CAM) and CNC milling, the Feed Rate () is the linear speed at which the cutting tool moves through the workpiece material. It is a critical parameter that, alongside spindle speed, determines the material removal rate (MRR), surface quality, heat generation, and tool life.
Calculating the feed rate is not a matter of guesswork; it is governed by the physics of chip formation. The fundamental equation for calculating the linear feed rate is:
