The relative motion between the cutting tool and the workpiece is called __________.
Feed rate
Cutting motion
Depth of cut
Rake angle
The relative motion between the cutting tool and the workpiece is called (a) motion.
The relationship between the main cutting speed VC, feed speed vf, and cutting speed ve in the figure is
Ve = Vc + Vf
Ve = Vc - Vf
Vc = Ve + Vf
Vf = Ve + Ve
