ДИНАМІЧНІ ІНВАРІАНТНІ ДИСКОВІ ВІДРІЗНІ ІНСТРУМЕНТИ
This work is aimed at improvement of durability of especially thin disc tools, by means of controlling their dynamic parameters. It was found out that it is necessary to design tools and methods of reducing oscillations of the tool’s structure that could allow designing tools with thin and especially thin cutting pieces, ensuring the specified parameters of its durability, cutting precision and improvement of cutting modes. The performed investigations allow to reduce substantially the cut’s width and ensure the prescribed parameters of the tool’s durability, thus improving the overall technical and economic parameters of blanks cutting.
