Abstract Because of the use of low-rigidity wire electrodes, wire is prone to bend and vibrate by various forces acting 由於線切割放電加工機的線電極並非剛體 ，加工過程 on the wire during Wire-EDM. Wire vibration and 中受外力的影響，便會導致線電極的撓曲及振動，進而造 deflection mainly cause contour inaccuracy during corner 成隅角加工精度降低，因此，本研究將針對尖銳隅角粗加 cutting. In order to improve the corner accuracy, a new path compensation strategy is introduced. Relation 工提出一新的軌跡補償策略以提高隅角精度。研究首先以 between geometrical contour error of inner corner and 田口式品質設計實驗計畫法來探討加工參數與隅角形狀誤 machining condition is investigated by the experimental 差間的關係，從變異數分析的結果得知，線張力與沖水壓 plan of Taguchi quality design. Through the quantitative 力是對於隅角精度影響最顯著因子，應用迴歸分析建立轉 analysis, the geometrical contour error is mainly a
