(1) using LP insert with radius 0,8 mm Note: During helical interpolation do not exceed maximum pitch When using HF insert or other different insert radius to calculate the ØDHmin and ØDHmax use the equation below: - Minimum Diameter: ØDHmin = 2 x (ØDc - (R corner radius + F width of edge wiper)) - Maximum Diameter: ØDHmax = 2 x (ØDc - R corner radius)
