Tool-path Generation for Groove Machining Feature

Abstract

Abstract In this study, algorithm in generating machining sequences and tool-path for groove machining features are developed. The algorithm is based on ruled-based method and enhancing automatic feature recognition (AFR) via volume decompositions method. From the position of the vertex in z-axis and x-axis directions, machining sequences can be determined, and machining features can be sorted out. From the sub delta volume (SDV) generated from the recognized features of 3D part model, vertex positions of each SDV is determined thus positioning of the tool-path can be obtained. To validate the generated machining sequence and tool-path, one workpiece has been assigned to the algorithm. This workpiece is also tested with commercial software CAM function. The result shows that the developed algorithm is capable in generating the tool-path and can be visualized.
