【Abstract】 In order to solve the questions of mechanical CAM tracking in automatic welding machine, a new way of electric CAM tracking is presented. Based on analyzing the constructive way of ellipsis, a mathematical model of position control is set up. The experiments using modified machine show that electric CAM makes little welding positional error and can meet the requirement of production.更多还原
