CAM system for cartesian-based robotic servo controller

This paper describes the development of a robotic CAM system for an articulated industrial robot from the view point of robotic servo controller. It is defined here that the CAM system includes an important function which allows an industrial robot to move along not only numerical control data (NC data) but also cutter location data (CL data) consisting of position and orientation components. In addition, the developed CAM system has a high applicability to other industrial robots with an open architecture controller whose servo system is technically opened to end-users. The developed robotic CAM system works as a straightforward interface between a general CAD/CAM system and an industrial robot. The basic design of the robotic CAM system and the experimental result are presented.
