Surface Finish Calculations


spacer The purpose of the surface roughness application is to enable the user to calculate the correct amount of lathe feed or ball nose cutter stepover to achieve a particular theoretical surface finish.
Calculations are based on the tool nose radius and feed per rev for turning, or ball nose cutter diameter and stepover for milling.
Calculations can be for inch or metric systems.
