Grinding Force Tangential

A new system for measuring a tangential grinding force using the slip of the rotational speed of an induction motor was developed. The motor slip is measured as the change in the rotational period for the induction motor. The system operates LabVIEW software on a personal computer, and a rotary encoder is connected with the motor spindle, which drives the axis of a grinding wheel
