MODERN TECHNOLOGICAL APPROACH TO ANALYSIS OF STRESS AND DEFORMATION OF LARGE DIMENSIONS SAW DISC

Summary/Abstract: The circular saw occupies a special place in the processes of cutting materials in a cold state ("cold saws"), as well as materials that are cut when heated to very high temperatures ("hot saws"). Hot saws cut off materials with different mechanical properties, various cross-sectional shapes, dimensions and positions on transport rollers. The saw blade is the most important part of a hot saw and represents a model of a rotating, thin, homogeneous plate structure. During the profile cutting process, the saw blade is exposed to variable resistances that cause different stressdeformation states in its structure, especially in the contact zone. The aim of this work is to confirm the hypothesis by strain gauge measurements that the stress-strain state of a thin saw blade plate mimics the so-called Flamant problem, which can be interpreted through the Hertz solution of the contact stress.
