RAD-6 (MRX) Helical Milling Conditions Sinking depth (h) when helical milling should be under Max D.O.C. in table below. Sinking angle a (with trajectory of the center line of tool) should be under a max (maximum ramping angle) in cutting conditions on page J20. Feed rate should be under 70% of cutting conditions on page J18. Climb milling is recommended. Formula for Sinking Depth (h) h = n x 0Ds x tan a (h should be under D.O.C.) la should be under a max) 0Ds (Trajector/ diameter of cutter's center line) 0Ds=0Dh-0D Requirements for Removing Core Inch Metric Inch Tool Spec.
