Implementing of photorealistic surface rendering in cam simulation

In this paper, different approaches to visualize CAM simulation results are presented. Simulated machined surfaces can be rendered in a photorealistic manner taking into account real tool motions and vibrations measured during the machining process. The actual tool trajectories are used to derive the microrelief of machined surface that lead to different reflective properties to be used in the CAM surface rendering pipeline. Broaching and grinding were two machining processes to adopt this photorealistic visualization. First, the generic CAM simulation computed the triangulated representation of the in-process workpiece. Second, the triangles were enriched with the computed micro topography information that is used by the developed shader implementation during the visualization process.
