  • Remove excessive chip accumulation with an air blast.
  • For the operation with depth of cut which varies (ex.casting skin) and machining of workpiece materials with interrupted surface, the feed per tooth (fz) should be set to the lower recommended value shown in the above table.
  • Cutting conditions may be limited depending on machine power, workpiece rigidity, and spindle output.  When the cutting width, depth, or overhang length is large, set Vc and fz to the lower recommended values and check the machine power and vibration.
