Guide for ramping (Slant milling) L Ramping angle should be RMPX (Maximum ramping angle) or under in the above cutting conditions. Reduce recommended feed rate by 50% RMPX Formula of the cutting length ap L = ap “L” at Max. ramping angle tan RMPX

Vertical milling (Plunging)

* For vertical milling (plunging), reduce feed rate to fz=0.1mm/t or less. Max. width of cut Insert description (ae) KCGT13 type 8mm

For helical milling, use between min. cutting dia. and max. cutting dia. Over max. cutting dia. Under min. cutting dia.

• Down-cut milling is recommended (refer to the figure above)
• Feed rate should be under 50% of the recommended cutting conditions
• Use caution to eliminate incidences caused by producing long chips
