The purpose of this study is to develop an in-process of measurement technique of surface roughness using thermoelectric effect in cylindrical grinding. The electromotive force (EMF) generates depend on the surface roughness of workpiece and the variation of workpiece temperature when the sensor with thermocouple wires rubs on the workpiece surface in grinding process. In this paper, the in-process measurement technique of surface roughness in cylindrical plunge grinding is proposed, conceiving the cancellation of the EMF caused by the variation of workpiece temperature in the sensor output. Also a new type in-process sensor was developed for high accuracy to overcome the problem which was clarified in the cancellation method of the influence of workpiece temperature at a basic sensor.
