具有比例法间隙补偿的线切割机床,在程序编制中必须增算一个比例圆半径R值。对应于圆弧的R值取圆弧名义尺寸;对应于线段的R值则应根据圆形不同类型用不同公式求得。R值大小则决定对应线段的变化量。其误差将直接影响其对应线段的精度。R值的误差是否会等于变化量的误差?它们之间存在什么规律?要保证R值的误差控制在线段精度的范围内,就必须明确这个规
With the proportional method of gap compensation wire cutting machine, in the programming must be added a radius of the proportion of radius R value. The R value corresponding to the arc takes the nominal size of the arc; the R value corresponding to the segment should be found by different formulas according to different types of circles. The value of R determines the amount of change in the corresponding line segment. Its error will directly affect the accuracy of its corresponding line segment. R value of the error is equal to the error of the amount of change? What is the law between them? To ensure that the error of R value control within the range of line accuracy, it must be clear that the rules
