Regrinding the conical cutting die increases the cutting clearance. This leads to a change in the smooth cut proportion or can lead to tolerance changes.

Ex. I With α = 10', the cutting clearance increases by 0.003 mm if the cutting die is ground down by 1 mm.
Ex. II With α = 30', the cutting clearance increases by 0.003 mm when the cutting die is ground down by 0.3 mm.
