In-process sensor for ground surface roughness is developed utilizing optical fibres. The sensor has a control system to keep the optimum distance between the fibre and the work. Disturbances of grinding fluid and swarf are avoided by such method that the measurement. is carried out in grinding. fluid. Two optical fibre bundles, one of them is normal to the target and the other is set with a certain angle against the first bundle, in order to increase the sensitivity, of the sensor. The output , of the latter signal is divided by the former output. Surface roughness is measured during cylindrical plunge grinding using the sensor developed in this study. Changing process of ground surface roughness is investigated for various grinding condition. Results are summarised as follows. (1) Improving rate of surface roughness is affected by depth of cut, and is hardly effected by work speed. (2) Surface roughness becomes constant after the surface layer of work which corresponds to maximum roughness is removed. (3) The constant roughness value mentioned above increases as depth of cut and work speed increase. Effect of work speed is more dominant than depth of cut.
