论测量基准与加工基准一致的重要性

The Importance of Consistency of Measuring Datum and Machining Datum

测量是决定加工质量的前提条件。通过分析三坐标测量过程,可得出测量基准对于测量结果影响的重要性。特别是对于高精度加工而言,不合理的测量基准选择将会导致对工件加工结果的误判,从而对生产设备进行误调整,加工出不合格的产品,对企业造成重大的损失。

Measurement is the prerequisite that determine the processing quality. We can know the importance which measurement reference influences measurement result by analyzing the CMM process. Especially for high- precision machining, the unreasonable measurement reference will lead to work piece machining results misjudgment, thereby misadjusting the manufacturing equipment, processing substandard products, resulting in significant losses for enterprise.
