Abstract
In this study, a drill dynamometer for measure dynamic forces and torques, using strain gauge transducers has been designed, manufactured and tested. The dynamometer is connected to a HMB data acquisition system. Drill forces signal are captured processed and transformed into numerical data with the help of hardware and software of the MGC. Plus acquisition system. The principle of the dynamometer measurement is based on strain gauge transducers which measures elastic deformations produced by the loads. The elastic element used in the construction consists in a spoked wheel which measures simultaneously the force and torque. The elastic deformations produced by the force and torque, bends the double embedded spokes. It is presented the dynamometer design and principle of measuring. In order to verify the elastic element deformations, it is performed a FEA analysis in ANSYS. The experimental model is calibrated and in the final stage is made experimental measurements of drill force and torque.
