a_p Axial depth for one circular/helical revolution: in. mm

Calculated value of axial depth of cut for one circular or helical revolution.

Length of one circular/helical revolution: in. mm

Calculated value for length of one circular or helical revolution.

Ramp angle at finished diameter of work piece: °

Ramp angle at rough diameter of work piece: °

f_n Advance: ipr. mm/min

n Spindle speed: rpm.
