  • Abstract

    At elongated holes boring several imperfections can occur, namely, the surface waviness and shape inaccuracies in the axial section. This research purpose is to establish the regularities of such imperfections formation depending on the technological system design parameters, on the processed material properties and on the cutting modes. Searching and establishing those common factors will allow, as early as at the technological process design stage, to choose the cutting mode optimal parameters as well as the cutting tools design parameters. As the research methodical basis, the method of horizontal boring operations mathematical modeling has been applied, taking into account the technological system variable rigidity. A mathematical model for predicting the surface imperfections formed when horizontal boring has been developed with the aim of such flaws occurrence further minimization. The developed model practical application provides the possibility to build graphs allowing the boring tool operator to choose rational cutting modes depending on the conditions of processing.
