Currently, the operation of grinding rolls of rolling mills using fine-grained wheels is the most advanced finishing method. However, the variety of recommendations for grinding with such wheels in the absence of process optimization techniques when trying to intensify the process lead to a deterioration in the output quality indicators. To determine the optimal grinding modes with fine-grained wheels using the linear programming method, a process model in the form of a system of linear inequalities and a linear optimization function was compiled based on technical limitations and experimental dependencies. Using the graphanalytical method, the optimal modes for grinding rolls with wheels 1-750×75×305 63S MI4 SM2 8B were determined by changing two mode factors (wheel speed and load on the electric motor of the wheel drive) and three grinding mode factors (part speed, longitudinal and transverse feeds). The optimality of the modes has been confirmed experimentally. Thus, the grinding mode determined by the linear programming method is indeed optimal, since it ensures the production of the part of a given quality at a lower processing cost.
