平面凸轮轮廓线检测数据处理方法研究

Study on Method of Data Processing in Measurement of Plate Cam Borderline

介绍了在平面凸轮轮廓线检测系统中所采用的数据处理方法 ,主要包括采样数据点的基于最小二乘法理论的三次非均匀B样条曲线拟合 ,以及补偿测头半径误差等方法的研究。该处理方法具有计算精度高 ,应用范围广的特点 ,可以为同类检测设备所借鉴。

A method of data processing applied to the measurement system of plate cam borderline is introduced in this paper,including the studies on fitting the sample data with cubic non-uniform B-spline curve based on least square method and radius compensation of the probe. The method has high precision and wide spread applicability. It can be used for reference by the similar equipment.
