1.控制测量技术的原理 图1所示为M131磨床使用外圆磨连续主动测量装置ZDW—L80和ZDK—L4控制仪的原理图。该装置的测量头随着被加工件尺寸的减小,测头磁芯位置将产生相应的机械位移变化,并通过这两只测头电感量的变化,将机械位移量转变成电量信号送到控制仪 1. The principle of control measurement technology Figure 1 shows the schematic diagram of M131 grinding machine using cylindrical grinding machine ZDW-L80 and ZDK-L4 continuous active measurement device. The measuring head of the device with the workpiece size decreases, the probe core position will produce a corresponding mechanical displacement changes, and by the changes of the two probe inductance, the mechanical displacement into electrical signals sent to Controller
