Teleoperation Robot Machining for Large Casting Components

Casting is an important means of components manufacturing. However, the machining of residual characteristics (RC) is a long-standing challenge, especially for large casting components. The reason is that the RC of casting components are different in size, complex in shape and random in distribution. It is difficult to deal with that by manual, serial robots, or machine tools. To address this problem, this paper proposes a robot-based teleoperation machining approach. A novel five degrees of freedom (5-DoF) hybrid machining robot developed by us is utilized as the slave robot. Then the teleoperation machining experiment of a large casting planet carrier was carried out. The results show that the machining efficiency is improved by about 10 times and the completion rate is above 95%. This provides a new idea for the machining of large components.
