Study of Magnetoelastic Torque Sensor for Cutting Processes Monitoring

Abstract:

This paper deals with the head-type torque sensor, on the basis of magnetoelastic effect, installed on the main shaft of machine tool for sensing cutting torque in order to monitor cutting process. The tests of two types of sensor are carried out under various cutting conditions. In order to confirm the accuracy of these sensors measuring cutting torque, the torque values obtained by two types of magnetic torque sensor are compared between measuring value of strain gauge and calculating value of cutting force experimental formula. The investigation demonstrates that the on-line monitoring of cutting force can be detected through measuring cutting torque by means of magnetoelastic torque sensor, and the cutting state can be shown by cutting parameters.
