Enlargement of the cutting clearance by regrinding
12.4.3
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.
Eqn. 1
Cutting gap change | Δ uS | = | mm |
Elevation change | Δ h | = | mm | |||
Angle | α | = | ' |
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.
