Abstract: The paper describes an adaptive control method in machining fiberglass parts made of composite polymeric materials. Composites have a number of significant advantages over conventional structural materials; they are characterized by low specific weight, high strength, corrosion resistance, transparency to electromagnetic radiation. But at the same time there are also disadvantages: anisotropy, difficulties in machining, tendency to delamination, low rigidity, etc. A non-rigid part under the cutting force deforms, which leads to a deviation of the machined surface shape. In this regard, the aim of the work is to develop a science-based adaptive control method of the cutting process in machining composite materials parts. The research is performed using the basics of automatic control theory, finite element method, methods of mathematical analysis and experiment. The adaptive control method is based on the technique of ensuring constancy of cutting force on the whole section of the machining surface. The proposed method allows the choice of machining mode and its change by controlling the working bodies of the machine tool on the basis of stabilization of elastic squeezes in the technological system through the controlled cutting force to ensure acceptable values of the deviation of the shape of the machined surface

Key words: machining composite material adaptive control shape accuracy cutting modes
