Reference data for ramping

Decrease ramping angle if chips become excessively long.

Guide for ramping (Slant milling)

L Ramping angle should be RMPX (Maximum ramping angle) or under in the above cutting conditions. Feed rate should be 70% or under of the above cutting conditions.

Formula of the cutting length ap L =

“L” at max. ramping angle tan RMPX RMPX

ap Guide for helical milling For helical milling, use between min. cutting dia. and max. cutting dia. øDh (Machining dia.)

Description Min. cutting dia. Max. cutting dia. Sinking depth at helical milling should be max. ap (0.5mm) or under.

• Down-cut milling is recommended (refer to the figure above).
