Abstract
Error estimation and compensation algorithm for tooth form grinding works of a helical gear is proposed. Tooth profile ground by a formed wheel is modeled by truing parameters and setting parameters of the grinding wheel. Actual tooth form is measured by a touch probe on the machine. The truing and setting parameters are estimated by fitting the modeled surface to the measurement data as the distances between the modeled surface and the measurement points coincide with the probe radius. Error propagation analysis from measurement errors to the estimation errors of the parameters is applied and suggests robust measurement algorithm. The proposed method was applied to the actual grinding process. The truing and setting errors were measured and compensated within 10 micrometers.
