Abstract

A dynamometer has been constructed for the measurement of axial drill force and torque during the drilling of Kevlar 49 composites. Initial tests of the dynamometer showed a significant time delay on the torque output channel.

Consideration of the equations of motion of the force transducer elements has enabled an analysis of the dynamic response of the instrument. This has led to improved transducer design and allows prediction of the dynamic interaction between the transducer elements and other components of the overall system. In particular the likelihood of severe dynamometer output attenuation due to operation in the vicinity of structural resonance of large relative amplitude.
