Heat treatment for car body's mold is mainly a manual process which is performed by worker. The performance of this process is affected by workers' skill level, and has limitation to maintain uniform product quality. In this study, we developed high frequency heat treatment robot system that implements OLP type simulator to overcome the limitation of manual process, and to improve and stabilize the quality level. Also, we plan to verify the efficiency of robot system and mechanism stability from the early stage through design verification and simulated analysis in development stage. In addition, we plan to study the way to establish optimized D/B for heat treatment criteria for car body mold such as heat treatment speed, interval, etc. via site experiment.

The manual mold heat treatment is affected by workers' skills so maintaining consistent quality is limited. To overcome the limitations of such a manual process and to improve and stabilize the quality of heat treatment, in this study, the composition of the efficient heat treatment system will be investigated by adopting the robot automation system with the exclusive robot and heat treatment automation process. In order to overcome limitations of the precise heat treatment adopting a manual type, this study will cover the virtual working process and the dedicated robot system for heat treatment with OLP(Off-Line Programming).
