RATING OF SAWS BY QUALITY AND MANUFACTURING ACCURACY BASED ON STATISTICAL CHARACTERISTICS

Abstract

The article highlights the issues related to the properties of circular saws, in particular the accuracy of their manufacture and subsequent sharpening. Wood-cutting tools must ensure high labor productivity and product quality, which depend on their durability and resistance to wear. The properties of circular saws from well-known foreign manufacturers were evaluated for compliance with their regulatory and technical documentation, the accuracy of manufacturing and sharpening of flat and trapezoidal teeth, composite technical and economic indices, and ultimately an integral indicator that combines all of the above technical and economic indicators. In a new circular saw, the carbide blades must have the same overhang to the left and right of the blade. If this rule is violated for various reasons, the accuracy and quality of the cut decreases during sawing, chips and other defects are observed, which ultimately negatively affects the tool's properties.
