金属切削测力仪是研究金属切削科学的重要实验工具,而测力仪各向之间的相互干扰,一直是影响测试精度的一个重要因素。为了提高测力仪的测试精度,人们对常用的电阻应变切削测力仪,在结构设计、电路连接及贴片技术等方面都作了许多研究,但测力仪各向之间的相互干扰,仍难避免,需要对测力仪的三向读数进行补偿。 Metal cutting dynamometer is an important experimental tool for the study of metal cutting science, and the mutual interference between the dynamometer and each instrument has always been an important factor affecting the test accuracy. In order to improve the testing accuracy of dynamometer, people made a lot of researches on the commonly used strain-gauge dynamometer, in the aspects of structural design, circuit connection and patch technology, but the mutual interference between dynamometer, Still difficult to avoid, the need to compensate for the three-way dynamometer readings.
