  • Attention for profile milling
  • Ramping
  • Helical interpolation
  • Calculation of tool pass dia.

φdc = φDh − φDc Tool pass dia. Bore dia. Tool dia.

  • Depth of cut per one circuit should not exceed max. depth of cut ap.
  • Down cutting is recommended, so tool pass rotation should be counterclockwise.

◎ In case of ramping and helical interpolation, apply 70% or less feed speed from standard cutting condition table.
