车床上由于实际加工精度的要求,往往纵横向脉冲当量不相等。欲使工作台沿给定的直线段或圆弧运动,现成的插补公式该作哪些修正?下面对直线和圆弧分别加以讨论。 1.工作台走直线时,着纵、横两方向(图1中X、Y方向)脉冲当量相等,即:0. 01 mm/脉冲(或步)= ,则偏差定义为; 即 .由偏 Lathe due to the actual processing accuracy requirements, often vertical and horizontal pulse equivalent is not equal. What is the correction of the existing interpolation formula for the workbench to move along a given straight line or arc? The straight lines and arcs are discussed separately below. 1. Workbench to go straight, the vertical and horizontal directions (Figure 1, X, Y direction) equal to the pulse, that is: 0.01 mm / pulse (or step) =, then the deviation is defined as;
