摘要
用极坐标与直角坐标法相结合，来解决沟中心定位不准造成测量误差太大的问题。描述了采用三个步进电机经过细分后驱动工作台沿Ｘ、Ｙ 方向移动来准确定位工件，实现了自动化测量。引进了光栅技术测量沟位置和沟中心距，推导出了测量沟中心的数学模型和最小二乘圆的公式。附图６ 幅。
The method which combines pollar coordinates with rectangle coordinates is to be used to solve the problem that the measuring error is too much because of uncorrect fixed position of groove center. The paper describes adopting three stepping motors which have been carefully divided to drive working table moving along X、 Y directions to make fixed position of the workpiece correctly, so that the automatic measurement is to be realized. The grating technology is introduced to measure groove position and groove center distance. The mathematics model of measuring groove position is established and the formula of least square circle is inferred.
