Abstract
The article presents the choice of optimal method of treatment when restoring of mill trunnion based on hierarchy analysis method. The criterion for selecting optimal cutting conditions is synthesized and their relationship with processing parameters is described. Many alternatives for solving a multicriterion optimization problem are constructed, methods of processing with variable cutting conditions are proposed. Based on selected criteria, a subset of Pareto-optimal cutting conditions is found when restoring trunnion. The method of hierarchy analysis is prese000nted as a multi-criteria method of decision-making using the algorithm for assessing the degree of consistency of paired comparison matrices. The applied method of expert evaluation selects the processing parameters with a decrease in the complexity of restoration work with preservation of quality of the processed surface of mill trunnion.

Summary
In the production of building materials for grinding raw materials ball mills are used, the technical condition of which is characterized by long-term operation with significant wear of the predominantly mechanical part of rotating support parts – trunnion. The add-on machine allows you to process trunnion mills at the site of operation [1]. The use of a rotary cutter allows you to improve the efficiency and productivity of the process, tool life with a high level of accuracy and quality of the machined surface. The decisive parameter in the rotational processing is the depth of the cut, the frequency of rotation of the axis, the speed of rotation of the workpiece and feed. The ability to vary the cutting conditionsallows you to achieve a given accuracy and quality of processing cylindrical surface and maintain high tool performance
