The purpose of this paper is to develop an automatic measuring system based on the optical Fourier transform which can be applied to the inprocess measurement of the characteristics of grinding wheel surface. The power spectrum pattern of grinding wheel surface which is observed by the optical method has some informations with respect to the characteristics of grinding wheel surface, i. e., the width of grain wear flats, the area of worn grains and the number of worn grains. In this paper, the power spectrum pattern measuring device which can estimate quantitatively and directly the characteristics of grinding wheel surface during grinding operation is introduced. And the in-process measuring system is proposed, which consists of a microcomputer, pitch control device, digital memory, rotary encoder, optical device and laser source etc. By developing the in-process power spectrum measuring system as mentioned above, the life time of grinding wheel can be determined in real time from the average width of grain wear flats and the state of grinding operation can be estimated from the distribution maps of worn grains around the grinding wheel surface printed by a teletype.
