Surface quality formation at polymer composite details' abrasive processing

The article presents the results of studies of the process of abrasive processing of parts made of polymer composite materials. Special features of processing of polymer composites, technology of production of preform by hydroabosive cutting are described. Studies have been carried out and stages of preparation of a part made of polymer composite material for "gluing" operation have been described. Dependencies for determination of surface roughness during hydroabrasive cutting of polymer composite material are given. Studies have been carried out to achieve the necessary surface roughness when gluing blanks. A curvature is given describing the surface roughness, which is necessary to achieve a reliable adhesive connection. Results of theoretical and experimental studies of hydroabrasive cutting process are presented. Technique of the execution, applied tools and equipment are described. The results of theoretical and experimental studies were compared. Their high convergence has been established. The results of experimental studies on preparation of parts from polymer composite materials for gluing are presented. Abrasive tool, processing modes are selected. Design method for abrasive processing of parts made of polymer composite materials is proposed.
