Abstract (English):
It is shown in the paper that the functionally-directed technologies of tooth working in spur gears should be supplemented with the technologies of the second order which ensure machining quality increase and an efficient operation of gear-milling tools. In particular, there is investigated the producing surface distortion of a hob caused by regrinding its front surface. It is shown that for the compensation of this distortion at wheel machining it is expedient to correct an installation angle of the axis in a miller regrinded repeatedly. The conditions are determined (types and grades of accuracy for millers) at which such a correction is necessary.
