What Effect Does the Rake Angle Have on CNC Cutting?

In machining, the rake angle is a parameter used in various cutting processes, describing the angle of the cutting face relative to the workpiece. There are three types of rake angles: positive, zero or neutral, and negative. Positive rake: A tool has a positive rake when the face of the cutting tool slopes away from the cutting edge ...
