Spindle Speed
Spindle function controls the spindle speed (S), the unit of spindle speed is r/min. Spindle
speed is the cutting speed when it is at the constant speed, the unit of speed is m/min.
S is modal G code command; it is only available when the spindle is adjustable. Spindle
speed programmed by S code can be adjusted by overrides on the machine control panel.
