金属旋压是一种塑料成型工艺，通过使用滚轮工具将金属压到旋转心轴上来形成金属板。设计了一种新型金属旋压机，其中罗拉由直线电机直接驱动。我们的目标是通过控制滚轮的推力使滚轮能够快速跟踪芯轴变化的半径来成型非轴对称产品。我们的实验结果表明，直线电机大大提高了力控制的响应，并且可以快速成型非轴对称产品。还研究了不带力传感器的开环力控制。在成形时间方面，它表现出与闭环控制相当的性能
Metal spinning is a plastic forming process that forms a metal sheet by forcing the metal onto a rotating mandrel using a roller tool. A novel metal spinning machine was designed in which the roller is directly driven by linear motors. We aim to form non-axisymmetric products by controlling the pushing force of the roller so that the roller can quickly track the changing radius of the mandrel. Our experimental results show that the linear motors substantially improve response of the force control and non-axisymmetric products can be rapidly formed. Open-loop force control without a force sensor was also studied. It exhibited a comparable performance to closed-loop control with regard to the forming time
