三坐标测量机系统控制及曲线曲面测量

Automatic control of coordinate measuring machine and measurement of curve and surface

基于三坐标测量机,从测点布置和测量路径设计出发,分析了曲线、曲面轮廓自动控制测量方法,实现了对各种自由曲线及曲面的测量.对凸轮、叶片等实例的分析表明,利用该方法可以快速编辑数据以进行高质量、复杂表面的模型重构,从而有效降低了由于操作人员的差异所引起的随机误差.该方法系统误差来源单一,测量结果具有更高的置信度.

Based on three coordinate measuring machine,the automatic control measurement of the curve and surface profile are analyzed by the measuring point distribution and the path design,and the measurement of various curves and surface is realized.Analysis of cam,leaves,and other examples show that using the method can quickly edit data so as to carry out high quality and complex surface of model reconstruction,then decrease the random error caused by the difference operator.The error source of the method is single and the measurement results have higher confidence.
