A Re-evaluation of the Initial Mathematical Model for Triangular Pocket Machining Strategy

In this paper, we aim to compare the tool path lengths that produced by the direction-parallel or zigzag or staircase strategy and contour-parallel strategy using a single cutter in the triangular pocket machining. The pocket geometry is chosen in such a way that the machining strategy can be carried out by single chisel. The mathematical model for chisel path length of machining process is developed then is used to contrast the chisel path length of two strategies. The specific purpose is to select the strategy that take a shorter chisel path. Based on the two numerical examples, the contour-parallel machining strategy gives the tool path length shorter than the zigzag strategy.
