摘要
本文在全面分析关于机械加工中定位误差产生原因有关例证的基础上,对工件在调整法加工中产生定位误差的原因作了较为深入的分析。并得出了判断产生定位误差的充要三条件和产生定位误差的根本原因。
Based on the analysing some examples of the positioning error caused by machining,
the reasons of positioning error are analyzed in detail. Three necessary and sufficient
conditions of decision positioning error and the essential reason causing posifioning error
are described.
