A New Conversion Matrix Model of Strain-Gage Dynamometer

Abstract:

Dynamometer has a extensive application in high-speed milling. The high frequency dynamometer is a kind of strain-gage dynamometer and produces a relation between the cutting force and voltage. And the relation can be expressed as a conversion matrix model which makes a great impact on the results of measurement. Taking into account cross-sensitivity and point effect at the same time, a new conversion matrix model for the high frequency dynamometer was established in order to improve the accuracy of dynamometer and the dynamometer has been subjected to calibration experiments to obtain conversion matrixes of the model. Finally, a series of high speed milling experiments were conducted. And the results obtained showed that the dynamometer by adopting the model could measure the cutting forces and have a higher accuracy.
