Current state-of-art CAM systems generate piecewise linear (G01-based) tool paths that lack G1 and G2 continuity. This paper presents a systematic solution of tool path B-spline fitting for improving the continuity and quality and a tool set to evaluate the quality of either G-Code commands or CNC-interpolated axis motion commands. The core of the solution(More)
This paper presents a novel geometric simulation technique for multiaxis Additive Manufacturing (AM). In the proposed methodology, additive swept volume elements, which are represented with Tri-dexel models, are formulated for updating the virtual additive material. Triangular meshes are extracted from the Tri-dexel models using Marching Cube Algorithm for(More)
