Abstract
This paper describes a research on a prediction of contact between a grinding wheel and a workpiece. The phenomenon of whitening of a grinding fluid, accompanied by the wheel approach to a workpiece can be detected using a laser sensor. The laser stripe is illuminated on the trailing flow of a grinding fluid and the reflection energy is measured. The illuminating and sensing point for an appropriate measurement is experimentally investigated. Effects of the distance between a wheel and a workpiece, wheel speed, and fluid flow rate on the laser reflection intensity is investigated, and the possibility of the prediction of contact is discussed.
