摘　　要：在机械加工及检验中,经常遇到某些尺寸不便于测量或某个平面不便于定位,必须通过其他尺寸的测量或其他平面的定位平间接保证该尺寸,这样就出现基准不重合现象。当按工序尺寸加工测量来间接保证原设计尺寸要求时,就容易出现产品误废的情况。In machining and inspection, often encounter some size is not convenient to measure or a plane is not easy to locate, must through the other dimensions measurement or other plane orientation flat indirectly ensure that the size of this benchmark is not coincidence. When processing according to procedure dimension measurement to ensure that the original design size indirectly when required, are prone to the condition of the false waste products.
