Industrial robotic system programmed from CAD files - an update

摘要

Purpose - In this paper a solution capable of extracting robot motion information from CAD data is briefly presented and explored. Design/methodology/approach - The motion information is added by the user to the CAD file, defining in this way the approach, fly-by and welding trajectories. So the user programs the robot. An application is then used to extract that information and constitute a pre-program, which should be tuned with the real robot using a small set of rules. In this way, versatility of robotic cells is improved and its programming is simplified. Findings - The developed CAD interface is tested using a robot welding experiment on a steel beam used for industrial buildings. Originality/value - This paper builds on work previously described in "CAD interface for automatic robot welding programming" published in Industrial Robot, Vol. 31, No. 1.
