<jats:p>An analysis of possibilities for the selection of tool geometry parameters was made to reduce tooth profile errors during grinding of gears by different methods. The selection of parameters was based on the analysis of the grid diagram of a gear and a rack. Some formulas and graphs are presented for the selection of the pressure angle, module and addendum of the rack-tool. The results of grinding of experimental gears confirm the theoretical analysis.</jats:p>
