Relation between geometrical contour error of inner corner and machining condition is investigated by the experimental plan of Taguchi quality design. Through the quantitative analysis, the geometrical contour error is mainly affected by wire tension and flushing pressure. By regression analysis, a mathematical model is established to estimate cutting path error of corner cutting. According to the estimated cutting path error, the program path is corrected.

研究首先以田口式品质设计实验计画法来探讨加工参数与隅角形状误差间的关系，从变异数分析的结果得知，线张力与冲水压力是对於隅角精度影响最显著因子，应用回归分析建立转角加工路径误差量估测模式，利用此模式以预测不同加工条件下隅角加工路径误差量，依据预测加工路径误差量计算轨迹补偿量，实验结果证明本文所提出轨迹补偿策略可有效提高60%之隅角加工精度。
