游标卡尺测量误差的原因分析

Analysis of Causes for Measuring Errors of Vernier Calipers

通过卡尺结构、示值误差测量结果不足情况分析可知游标卡尺测量误差主要来源于:量具的握法、游标卡尺的零位误差、测量力的大小、读数方法、使用方法等因素,正确地使用游标卡尺需要注意正确的握法、正确的零位校准、测量过程的正确把握、正确的读数方法才能够得到正确的测量结果,使加工制造、测量检验满足实际工作的需要。

Through the analysis of the caliper structure and the insufficient measurement results of the indication error,it can be seen that the measurement error of the vernier caliper mainly comes from he following factors:the grip method of the measuring instrument,the zero error of the vernier caliper,the size of the measuring force,the reading method and the use method.The correct use of vernier calipers requires attention to the correct grip,correct zero calibration,correct grasp of the measurement process,and correct reading method to get the correct measurement results,so that the manufacturing,measurement and inspection can meet the needs of actual work.
