基于两步法误差分离原理的圆度仪误差分离系统 ,克服了传统的“多步法”分离过程中存在的“谐波抑制问题”,缩短了分离时间 ,有效地抑制了分离过程中引入的测量噪声及系统漂移的影响。该装置不仅可以使圆度仪主轴回转误差从被测工件测量结果中可靠分离 ,而且整个测量过程实现了全自动无人操作 ,提高了系统的抗干扰能力及可靠性 The roundness meter error separation system based on two-step error separation principle overcomes the “harmonic suppression problem” existing in the traditional “multi-step method” separation process, shortens the separation time and effectively restrain the introduction of Measuring noise and system drift effects. The device can not only make the roundness of the spindle rotation error from the measured workpiece measurement results reliable separation, and the entire measurement process to achieve a fully automatic unmanned operation and improve the system’s anti-interference ability and reliability
