The Classification of Abrasive Wheels by Topography of the Ground Surface of R9M4K8 Plates Using Cluster Analysis

Modern engineering often faces the problem of product classification according to various criteria. In this study, the authors used hierarchical cluster analysis to form groups of abrasive wheels based on the quality of ground surface of R9M4K8 plates. The wheel cutting capabilities were evaluated by surface topography of the parts. Roughness parameters, deviations from flatness, and microhardness with regards to location and dispersion were taken into consideration. It was established that abrasive tools could be classified into three clusters: 1 — 5NQ46I6VS3, 5SG46K12VXP, TGX80I12VCF5, 25AF46K10V5-PО3, 5A46L10VAX, EKE46K3V, 34AF60K6V5; 2 — 5SG60K12VXP, 5SG46I12VXP, 25AF46M12V5-PО3, 92A/25AF46L6V20; 3 — 25AF46M12V5-PО, 25AF46M10V5-PО3, 25AF60M10V5-PО, 25AF46M10V5-PО3, 25AF46L10V5-КF35. It was determined that the wheels of the first cluster provided the smallest parameters of roughness and deviation from flatness when grinding R9M4K8 plates, while the wheels of the third cluster improved the parameters of microhardness and the deviation from flatness.
