Data Processing of Laser Metal Deposition Shaping Technology: Part II. Contour Scanning Path Research

Abstract:

This document proposes a kind of contour path offset algorithm of Laser Metal Deposition Shaping (LMDS) technology. The contour path offset is determined by both laser spot radius and post-processing allowance. Besides, the offset direction can be judged through applying the cutter offset principle of NC machining. Then the formed intersecting points of a series of equidistant lines can be connected circularly to solve the contour path offset line. Since this algorithm fully considered the near-net shaping condition of LMDS and the combined effects of laser spot radius, the precision of as-formed metal parts could be further improved.
