Abstract

The quality of tool paths is a dominant factor in CNC machining, determining its efficiency and accuracy. This paper provides a brief review (in Chinese) on tool path planning methods reported in the literature, focusing on their categorization, motivating problems/issues, and historical development. Some promising research trends have also been stressed, especially for the paradigm shift from tool path generation towards tool path optimization.
