介绍一种快速、精确的在线测量圆柱工件直径的方法—V型座测经法.对测量原理和误差进行了分析,指出在顶角为60°的V型座测量椭圆度较小的圆柱工件时,随机一次测量结果即可视为其平均直径,测量误差已可忽略。
A rapid and accurate method for on-line measurement of cylindrical workpiece diameter -V-type seat-measuring method is introduced.Measurement principle and error are analyzed.It is pointed out that a V-shaped seat with apex angle of 60 ° can measure cylindrical workpiece with small ovality When a random measurement results can be regarded as the average diameter, measurement error has been neglected.
