Abstract
The aim of tool path planning is to maximize the e�ciency against some given precision criteria. In practice, scallop height should be kept constant to avoid unnecessary cutting, while the tool path should be smooth enough to maintain a high feed rate. However, iso-scallop and smoothness often con ict with each other. Existing methods smooth iso-scallop paths one-by- one, which makes the �nal tool path far from being globally optimal. In this paper, a new framework of tool path optimization is proposed, where di�erent objectives can be considered simultaneously, to plan globally optimal tool path with respect to iso-scallop and smoothness. The idea is to view a family of iso-level curves of a scalar function over the surface as the tool path so that desired tool path can be generated by �nding the function that minimizes certain energy functional. The energy functionals for planning iso-scallop, smoothness, and optimal tool path are respectively derived, and the path topology is studied too. Experimental results are given to show e�ectiveness of the proposed methods.
