摘要：The present invention provides a method of cutting a workpiece efficiently withhigh accuracy by utilizing tension adjusters to approximate tension in a wire in a wire saw
to a predetermined target tension while effectively reducing only tension in a winder-sidewire. The method comprises a forward-driven cutting step of cutting a workpiece whilemoving a wire forward, a first switching step of reversing a driving direction of the wire, abackward-driven cutting step of cutting the workpiece while moving the wire backward,and a second switching step of reversing a driving direction of the wire and returning tothe forward-driven cutting step, the steps being repeated in this order. In both switchingsteps, only tension in a winder-side wire is reduced by tension manipulators. A reductionin target wire tension therefor is performed after completion of deceleration of the wirein each switching step.
