✦ Synopsis

This study investigated how various process variables such as speed of the tool center paint and payload affect robot mpentability. The study was a simulated multistatioa assembly operation done on a flat table top. Variouscombinations of the process variables were used for the study. The results of the investigation showed that these process variables affect robot performance in varying degrees, with higher speeds and weights having the most significant effect. The repeatability of the robot deteriorated as the speed increased beyond 50% of the status speed (508 mm]s) and the weight inerensed beyond 0.91 kg. The findings do not support what might he n general practice of selecting robots with higher speed or payload over those with lower ones, everything else being equal This is impartant to the production engineer concerned with the deployment of robotic systems.
