Data Processing of Laser Metal Deposition Shaping Technology: Part III. Filling Scanning Path Research

Abstract:

This document investigates two kinds of generation algorithm of filling path, namely the subarea parallel reciprocating scan and the contour parallel scan, and proposes a kind of generation algorithm of subarea scanning vector. In the process of the generation of scanning vector, this algorithm has no need to perform area judgment to every scanning vector, and promotes the algorithm efficiency. Meanwhile, the connecting path between scanning areas was optimized, thus reducing the empty run, increasing the machining efficiency, and further improving the forming quality of the inside of metal parts.
