METHODOLOGICAL ASPECTS OF DESIGNING A DIGITAL MODEL OF TWO-SIDED FACE GRINDING TREATMENT
The paper is devoted to the development of methodological foundations of digital models of two-sided face grinding treatment. The study objective is further increase in the effectiveness of work preparation of two-sided face grinding in the conditions of automated and digital manufacture. At the present stage of the development of mechanical engineering and computerized manufacture the technological parameters of adjustment and cutting modes of metalworking systems should be determined not by reference data, but as a result of simulation modeling of treatment processes taking into account all actual technological factors of influence. The problem to which the paper is devoted is the search for solutions to the problems of ensuring the correctness of mathematical and computer models being developed, adequate consideration of dominant factors, correct representation in the digital form of treatment process of patterns, relationships and constraints taking place based on the methods of structural parametric analysis and simulation modeling. These problems can be solved only on the basis of a systematic approach to the treatment and the development of methodological foundations for creating its digital model, which is the subject of research in the presented paper in relation to two-sided face treatment (FT). The following things are proposed: an algorithm of structural and parametric FT design, a structural and functional model of workpiece forming, objects and connections of technological interaction in FT, which together are the methodological foundations for the virtual FT presentation and have signs of scientific novelty. The results of virtual FT of cylindrical rollers in production conditions and the technical settings of the machine found on the basis of the stated methodological recommendations show that the required values of the dominant shape errors and the relative position of the treated surfaces are provided within the specified constrains. Conclusions: the provisions given in the paper and the model environment can be used in the development of an automated system for technological FT preparation in the conditions of digital production.
