Effect of the Change of welding torch and piece arrangement by the 3-dimensional robot welding simulation

3차원 로봇용접 시뮬레이션에 의한 용접토치 및 부재배치의 변경에 따른 영향 평가

This simulation was carried out to estimate the process time and to improve the operation efficiency. The subassembly process consists of piece arrangement, tack welding, robot welding, manual welding and the robot welding of them was the focus of the simulation. Robot welding stage was analyzed by UML and IDEFø method, and then it was represented as the three-dimensional model(simulator) based on the analysis. The output of this simulation was the cycle time for one day's work. The cycle time for the different torch and the different piece arrangement was investigated by the 3-dimensional simulation.
