Synthesis and Generation of Surfaces Milled by Ball Nose End Mills Under Tertiary Cutter Motion

Abstract

The synthesis and generation of milled surfaces under tertiary cutter motion of the spindle with ball nose end mills was investigated and shown that a multitude of surface topographies can be generated. A basis for theoretical investigation was established by the derivation of the tooth path equations and the development of computer simulation models for ball nose end milling processes. The accuracy of the developed computer model and the feasibility of the tertiary cutter motion concept were subsequently authenticated and verified by the agreement between the experiments and the computer simulations.
