The article describes the scheme for continual improvement of manufacturing quality spur gears in terms of error profiles of the side surfaces of gear teeth. The technique is universal and applicable to any operations of gear processing. The practical application of the technique is considered by the example of gear milling with a worm gear cutter. The errors of profile include metrological indicators of total error profile, the error direction and error of form profile. The scheme of analysis of the data consists of several steps – evaluation of indicators relative to the limit values, identification of the technological structure of the profile errors and expert analysis of the profile profilograms. The final expert analysis of profilograms allows to reveal the most probable operating negative technological factors leading to deviations of a profile from nominal position. The advantage of the quality improvement scheme is its high efficiency and effectiveness in comparison with traditional methods of statistical quality management, since it does not require the collection of significant amounts of statistical information.
