Abstract
The goal is to develop an algorithm for implementing the edge quality management system for finishing parts with polymer-abrasive brushes, discussed in part 1. The principle of the system approach is used for a formalized description of the system with the presence of relationships between its constituent subsystems. The article considers the algorithm for designing the technological operation of edge processing in accordance with the optimal control system described in part 1. The initial data were: parameters of the workpiece, requirements for roughness and edge parameters, characteristics of tools and equipment. Based on the analysis of the functional capabilities of the operation, an algorithm for selecting the optimal tool among competing ones is obtained, taking into account the technological capabilities of the operation. Based on the developed mathematical models (formation of a rounded edge in size, shape and roughness, cutting force, temperature in the processing zone, tool wear), the optimization of technological parameters of the operation was carried out. The developed algorithm for designing a technological operation provides for conducting a test operation (installing and attaching the workpiece to the equipment, processing it at optimal modes) and monitoring the compliance of processing results with the requirements of regulatory and technical documents, analyzing defects and their causes, as well as forming a control effect. The control subsystem "Optimization of the process of rounding edges"is considered. Developed system for design of technological operations of processing of the edge elastic polymer-abrasive brushes allows you to assign the most effective tools and rational regime treatment parameters ensuring all requirements of normative-technical documents on the quality of processing at the highest productivity and lowest cost of operation.

Summary
Резюме: Цель – разработка алгоритма реализации системы управления качеством кромки при финишной обработке деталей полимерно-абразивными щетками, рассмотренной в части 1. В статье рассмотрен алгоритм проектирования технологической операции обработки кромок в соответствии с системой оптимального управления, описанной в части 1. Разработанный алгоритм проектирования технологической операции предусматривает проведение пробной операции (установка и крепление заготовки на оборудовании, ее обработка на оптимальных режимах) и контроль соответствия результатов обработки требованиям нормативно-технических документов, анализ дефектов и причин их возникновения, а также формирование управляющего воздействия. Разработанная система проектирования технологической операции обработки кромки эластичными полимерно-абразивными щетками позволяет назначать наиболее эффективные инструменты и рациональные режимные параметры обработки с обеспечением всех требований нормативно-технических документов по качеству обработки при наибольшей производительности процесса и наименьшей себестоимости выполнения операции. Система управления качеством кромки при финишной обработке эластичными полимерно-абразивными инструментами и ее анализ.
