当使用普通外圆磨床磨削圆柱体工件时,操作者通过调整上工作台的回转角以消除工件的锥度。然而,当工件两端直径调整到完全相等时,用量仪测量工件中段的几个截面直径,往往会发现其尺寸与两端不相等,而且彼此也有差异。若将各点在直角座标中标出并将其连接,即能表示出工件母线的凹凸情况。对圆柱体母线来说,就形成误差。这项误差是机
When using ordinary cylindrical grinder grinding cylindrical workpiece, the operator by adjusting the rotation angle of the table to eliminate the workpiece taper. However, when the diameters of the two ends of the workpiece are adjusted to be exactly equal, it is often noticed that measuring the cross-sectional diameters of the middle part of the workpiece by means of gauges will not be the same size and different from each other. If the points marked in the Cartesian coordinates and connect it, that can be expressed in the workpiece bump convex situation. On the cylinder bus, it forms an error. This error is machine
