A Strategy of Toolpath Generation for Finish Machining of Mold Cavity Based on Tool-Zmap Model

Abstract

A strategy of toolpath generation based on Tool-Zmap geometric model has been proposed to achieve efficient finish machining of mold cavity. Considering cutting tool wear, the finish machining of mold cavity was performed using variable cutting tools of different diameter. Each cutting tool only cuts the corresponding area to avoid identifying machining characteristic and poor rigidity of cutting tool during high speed machining. Finally, the validity of presented strategy was experimentally affirmed by a mach…
