It is difficult to judge the dressing timing of grinding wheel by beginners. The timing is usually decided based on many years' experience. This reseach is to find the standard of the dressing timing. Grinding sound, grinding force and surface roughness of workpiece are measured in surface grinder and mutual relations of these signals are investigated. The material of workpiece is S50C, SK3 and SKD11. The dressing timing is discussed. The following points are made clear. (1) The sound pressure level of grinding sound depends on the material of workpiece and the dominant frequency is different in material. (2) There are no steady relations among grinding sound, grinding force and surface roughness of workpiece. Therefore, it is difficult to predict the grinding condition by grinding sound only. (3) The dressing timing is to be realized by neural network method if the resuls of detaied experiment is obtained.
