摘要：In this study, the variation in diamond wire tension during the reciprocating wire-winding machining process is investigated to improve the cutting stability and machining precision of a reciprocating winding diamond wire saw. Furthermore, the main causes of wire tension variation are analyzed, a tension control method using a PI (proportional-integral) regulator is proposed, and a wire tension detection and control mechanism is developed to solve the problem of tension variation during the machining process. The performance of this mechanism is verified through experiments, in which polycrystalline silicon materials are cut. Experimental results show that the designed mechanism can effectively mitigate tension instability during the reciprocating wire-winding machining process, control the wire tension fluctuation within 0.6 N, and significantly improve cutting efficiency, cutting surface roughness, and machining dimension accuracy.
