位置度作为控制机械零件有关要素的相互位置关系及自身的位置,无疑是一个极为重要的綜合性指标。尤其当在滿足功能的前提下,采用最大实体原理,既有利于加工,也方便检測,給生产带来較大的經济效果。作为位置度的检驗方法,目前工厂采用的一般有:使用万能量仪的座标測量法,使用投影仪的投影检驗法或使用綜合量規的量規检驗法。但对于采用最大实体原理的場合,最为合适的检測方法应根据 Position as a control of the mechanical components of the relationship between the elements and their position, is undoubtedly an extremely important comprehensive indicator. Especially in the premise of meeting the function, using the principle of the largest entity, both conducive to processing, but also easy to test, to bring greater economic benefits. As the location of the test method, the factory generally used are: the use of multi-meter coordinate measuring method, the use of projector projection test or the use of integrated gauge test method. However, for the use of the largest physical principle of the occasion, the most suitable detection method should be based on
