Automated Reconstruction of Continuous Robotic Motion from G-Code Patterns

Abstract. Links between Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) packages have been established through translators and dedicated tools for decades. Tools such as CATIA © or Mastercam © allow users to generate toolpaths for a large variety of machines, while maintaining peculiar machine specifications. Current developments in open source manufacturing, driven largely by the 3d printing hobbyist community, are resulting in a booming of the toolpathing technology tools and applications for additive manufacturing. The emergence of open source tools for additive manufacturing, which often discretize continuous motion in finite linear segments, offer an interesting opportunity: these tools are optimized to fill or trace a defined surface or slice of which the bound is defined from an intersection with a simplified surface tessellation model. The latter contains a discretized solution of a parametric feature as defined by a CAD program. Therefore, these tools are ignorant of any potential parametric surfaces or curves present in the topology to be traced. For many, more industrial, machines, the discretized line segments which define an arc, spline or other feature are not optimized and neglect higher order functionality of the ability of the machine to be programmed.

Keywords. Feature Recognition, Process Planning, Numerical Control, feature extraction, Toolpath Optimization
