TITLE
Sensing Friction: Methods and Devices

ABSTRACT
Designing sensors to measure friction-stress in metal working has been pursued by many researchers. This paper discusses the genesis of some of the sensors which can now be used for research purposes. Two sensors, which are used in laboratories are: the pin-type sensor and the cantilever friction-stress sensor. Details of these devices will be discussed, for instance, the pin-type sensor measures two forces at the interface, one orthogonal to the rolling direction and the other at an angle to rolling and by converting the angular measurement, and comparing it to the normal force, the friction is eventually obtained. In the case of the cantilever sensor the friction stress is measured directly at the surface in orthogonal directions giving instant feedback on friction-stress at the surface. There will also be a very brief description of ongoing research and development on a diaphragm sensor, which shows considerable promise for the measurement of friction.
