During research two methods were compared. The first method is traditional researching the profile of the surfaces. The second is based on application of optical-electronic means and computer technologies. Results of comparison of a roughness of a surface after grindings by abrasive circles are presented.</p>A rollers with modified contacta roughness surfacessection gag logautocorrelation functionopticalelectronic methodБомбинированные роликишероховатость поверхностипрофилограммаавтокорреляционная функцияоптико-электронный метод
