摘　　要：镜像加工方法是一种解决大型薄壁零件制造难题的有效途径。为保证镜像加工过程中恒定支撑,基于镜像加工装备,设计了一种末端执行器。末端力传感器反馈的支撑力信息用于对当前位置的支撑力修正,以达到恒定支撑力的效果。并且提出了一种基于模糊自适应PID控制的在线轨迹修正位置/力控制策略,在LABVIEW中建立了测量控制模块,在镜像加工装备上进行了加工实验验证,结果表明:该方法能够实现精确位置跟踪和力跟踪控制。Mirror processing was an effective method for manufacturing thin-walled parts.In order to guarantee the constant force in the manufacturing process of the thin-walled parts,a terminal actuator is designed based on the mirror processing equipment.The force information fed back by strain sensor was used to correct the force of the predicted position so as to achieve a constant force in this way.And proposing an online trajectory correction position/force control strategy based on fuzzy adaptive PID block,establishing the measurement control module in LABVIEW,it could acquire the tracking precision and the tracking reference force on the milling machine for experimental verification.
