一种涡旋体轮廓精密原型测量系统

采用接触型红宝石探头沿X轴方向做匀速移动进行扫描测量，被测涡旋工件定位在精密旋转平台上，旋转平台的旋转速度和扫描探针移动速度按阿基米德螺旋线联动，通过探针的三维传感器输出和X轴位移传感器的输出能精密测出对应角度的涡旋半径，通过仿真对测量系统误差进行分析，且和三坐标测量机（CMMs）的测量结果进行对比。结果表明：原型精密测量系统的测量精度和CMMs相当，但测量时间大大缩短，基本上可以满足在线加工测量的需求。

A Precise Prototype Measurement System for Scroll Profiles

A contacted probe made in red diamond was used for measuring profile. The probe moves along X axis at a constant speed. The scroll work piece was fixed on the precise rotational stage. The relationship of stage rotational speed and x axis moving speed complies with Archimedean curve. A scroll radius for angle of correspondence can be measured by three coordinate output of probe and output of X axis displacement sensor. Measurement error of rapid measurement system was studied by simulation test. The measure...
