Construction Method of Tool Path Based on Arc-Cell

Abstract:

Tool path is usually described by means of continuous small linear segments. It results in large number of programming points in order to achieve high precision. A construction method of tool path based on arc-cell is presented in this paper, and the tool path is G¹ continuous. The construction method is applied to describe the tool path of wave shape specimen and hill shape specimen. For the two specimens, when their tool paths are described based on continuous small segments, 128212 and 184954 linear segments are necessary, respectively. But when their tool paths are described based on arc-cell, 15838 and 21669 arc-cells are necessary, respectively. And its more important that these arc-cells include information of curvatures and arc-lengths to control acceleration and deceleration.
