QUALIMETRIC ASSESSMENT OF THE QUALITY OF METAL-CUTTING TOOLS

Abstract

The paper analyzes the factors affecting on the efficiency of the metal-cutting tools. It is shown that the choice of rational mechanical properties, geometric parameters of the tool, wear-resistant coatings, cutting modes, etc. have a major impact on the efficiency of metalworking. It was established that it is necessary to change the concept of quality assessment of metal-cutting tools for improving technological processes of mechanical processing. An algorithm for creating a methodology for assessing the quality of metal-cutting tools has been developed based on the conducted analysis and the results of an expert assessment. An algorithm for comprehensive assessment of the quality of cutting tools was constructed in this work. It was determined that a complex quality indicator consisting of a set of single indicators should be applied for the qualitative assessment of the quality of metal-cutting tools. A hierarchical “Property Tree” diagram was developed to determine the factors affecting the overall quality of the metal cutting tools. It is proposed to use the requirements of the ISO 9001 standard to ensure the quality of metal-cutting tools. The investigated process should be considered as part of the organization’s quality management system. It is proposed to develop documented procedures for the rational management and continuous improvement of the procedure for assessing the quality of metal-cutting tools. The developed procedures will accompany the process of qualitative assessment of the quality of the metal-cutting tool.
