Guide for Drilling Depth of Drilling Refer to Max. Cutting Depth (Pd) shown in the lower table of M178. (Pd Shows the maximum plunge depth.) When Traversing after Drilling (1) Reduce the table feed by 50% until the center core part (do not forget to grind) is completely cut off. (The internal cutting edge's radial rake angle is large in the negative direction) (2) The min. cutting length “X” for flat bottom surface is as follows M178. Guide for Ramping (Slant Milling) Ramping angle should be under amax (Maximum ramping angle) in the above cutting conditions. Feed rate should be under 70% of the above cutting conditions. Formula of the cutting length “L” at Max. ramping angle ap tan amax Guide for Helical milling Sinking depth (h) at helical milling should be under Max. ap in the above cutting conditions. Ramping angle a (with trajectory of the center line of tool) should be under amax (Maximum ramping angle) in the above cutting conditions. Feed rate should be under 70% of the above cutting conditions. Down-cut machining is recommended. Helical Milling Factors Ds (How to find diameter of trajectory of tool's center line)
