Post processor for industrial robots — Circular arc interpolation of CLS data to generate FANUC robotic program —

In this paper, a post processor for an industrial robot FANUC R2000iC is introduced. Without conventional teaching process, the post processor regularly generates a robotic program written in LS format from cutter location source data called CLS data. The CLS data supporting “GOTO” and “CIRCLE” statements for linear and curved motions are easily made through the main process of CAD/CAM, so that a promising data interface between the industrial robot and CAD/CAM can be realized. The effectiveness is evaluated through simulations of trajectory following and an actual machining experiment.
