Product Quality Management Based on Monitoring the Working Process Execution Quality

The article addresses the task of ensuring part quality based on monitoring the working process quality and using it to make decisions about equipment serviceability. The relevance of the research is justified, focusing on the relationships between product quality indicators and equipment technical condition indicators, as well as the development of diagnostic methods that consider these relationships. These methods are based on continuous monitoring of equipment serviceability, automated data analysis and processing, enabling the forecasting of: the residual service life of machine components and assemblies under various cutting conditions, tool life, and the quality of machined surfaces throughout the mechanical processing. An analytical review of non-disassembly diagnostic methods is presented, which are developed for equipment lifecycle management and used in practice to organize Maintenance and Repair (M&R) based on a “serviceable / faulty” condition assessment. To ensure the required processing quality, it is proposed to determine the “timeliness” of M&R based on conclusions about the equipment condition according to the “operable / inoperable” criterion. In this context, the task of developing a method for diagnosing equipment condition under load and determining critical processing regimes is considered relevant. These are regimes where, due to vibration caused by wear of machine components and assemblies, the part quality indicators will not meet acceptable limits. Preferred (rational in terms of ensuring processing quality) and critical cutting regimes are proposed to be determined based on experimental data and their numerical processing. A description and algorithm for conducting the experiment are provided. A list of possible solutions and measures for product quality management is proposed for the case when the vibration level exceeds the limit value. Directions for the development of the proposed quality control method for practical application at engineering enterprises are identifed.
