Abstract. The profile gear grinding modes definition technique is developed to provide the uniform residual temperatures after heating and subsequent cooling which predetermine uniform thermal deformations on periphery of a cogwheel when grinding. The initial basis for this is a possibility to determine the gear grinding temperature both on the heating and cooling stages and, besides, it is may be also a choice of the operation cycle structure with and without the working stroke omission. In the interval of the profile gear grinding modes, two variants of the gear grinding working cycle structure with reciprocating displacement of the grinding wheel are considered using the simulation method with an omission and without one of the working stroke. Certain combinations of mode parameters are found in the range of their possible values at which the combination of heating and cooling leads to the lowest residual surface temperature both during and after working stroke.

Keywords: profile gear grinding, gear grinding temperature, heating stage, cooling stage, cycle structure, working stroke, temperature.
