  • Abstract

    The further magnification of efficiency of parts machining with little inflexibility demands the machining application of new technological solutions. The concept of suppression of the regenerative oscillations at the expense of modulation of cutting speed becomes one of such directions. Aim: The aim of the research is the development of the control system for milling machine tool, allowing to realize modulation of cutting speed under the periodic pulsing law with the given modulating depth and frequency. Materials and Methods: Development of the control system is made for the machine tool Micron OMM64SC with control unit of SINUMERIK 802D. Results: The theoretical fundamentals of given concept of suppression of the regenerative oscillations are developed; research works have confirmed the efficiency of its applications. Various alternatives of implementation of an additional correcting link of a control system by a cutting machine with function of modulation of cutting speed are observed in the paper. Advantages and deficiencies of each of alternatives are specified. The original block diagram of the system is resulted and the exposition of its practical implementation on horizontal milling machine OMM64 with CNC system of SINUMERIK 802D is resulted.
