Development of Reaction-Controllable Milling Head and Its Cutting Performance (2nd Report, Cutting Force Performance of Reaction-Controllable Head with Helical Milling Cutters)

摘要

A new milling head, which is able to control both cutting force and its locus, is proposed. The head has two helical milling cutters, which rotate in opposite wise through a pair of gears. Since both up and down cuts are carried on by each cutter at the same time, the sum of both cutting forces results in decreasing the resultant cutting force acting on the head and in changing the force vector locus. The force features by the head under selected cutting condition are numerically simulated through the cutting performance of single helical milling cutter with the energy approach method using two dimensional cutting data and experimentally discussed. The force and its locus can be controlled by the ratio of the up/down radial depth of cut and cutting edge phase.
