In the processing of gears by the form grinding method, the accuracy of the gear tooth profile is easily influenced by setting errors of grinding wheels. When the values of the coordinates and slope of the tangent at points on the cutting edge of a grinding wheel are given, the transmission of setting errors from a gridning wheel to a work is denoted by a matrix and analyzed. Using this method, the setting errors of the grinding wheel can be analytically calculated. The estimation of setting errors is performed on the basis of data of tooth profile error obtained in gear processing. The accuracy of the estimation is dependent on the number of data sampled from the tooth profile curve. The greater the number of sampling data is, the better the accuracy of the estimation becomes. It is possible to estimate from a few sampling data depending upon the grade of gear finishing. Processed examples based on this idea are shown. The results show that this estimation effectively maintains the accuracy of the gear in form grinding processing.
