日本三丰公司开发的LSM301N型激光扫描测微仪,可对圆柱形刀具误差实现在线测量。如图1所示,立铣刀在转动过程中,各刀刃与激光光线垂直时的尺寸S_1是各不相同的,其最大差值(S_1的变化范围)即为刀刃的径向跳动误差。测量S_1的同时,也可获得尺寸S_2的变化范围,即为铣刀直径误差。在图2中,所测尺寸S_2的变化即为刀具长度尺寸的变化,实际应用时,图2可用于测量刀具轴向长度因磨损等因素所需补偿量。若同时使用两台LSM301N,则可同
Japan’s Mitutoyo company developed the LSM301N laser scanning micrometer, cylindrical tool error on-line measurement. As shown in FIG. 1, the size S_1 of each end edge perpendicular to the laser beam during the rotation of the end mill is different, and the maximum difference (the range of variation of S_1) is the radial runout error of the blade. Measuring S_1 at the same time, but also to obtain the size S_2 of the range, that is milling cutter diameter error. In Figure 2, the measured size S_2 change is the length of the tool changes in size, practical application, Figure 2 can be used to measure the axial length of the tool due to wear and other factors required compensation. If you use two LSM301N, you can use the same
