Obtaining an accurate worm wheel requires a wheel model with the appropriate accuracy. This model can be obtained by computation, however, this is a complex and labor-intensive issue. In the CAD environment, there is a possibility of simple and quick modeling of the dentition, which is an alternative to mathematical calculations. It consists in creating micro surfaces and their approximation. The paper presents a comparative analysis of two methods of approximation of a discrete surface and the influence of modeling accuracy on the deviation of the profile of a wormwheel tooth was determined. It has been shown that the use of 30 surfaces allows to obtain the required accuracy of the outline.
