FORMALIZED DESCRIPTION OF THE PROCESS DESIGNING OF UNIVERSAL MODULAR FIXTURES Bogutsky V.B., Ph.D (Engineering), Associate Professor, e-mail: bogutskivb@yandex.ru Sevastopol State University, 33 University st., Sevastopol, 229053, Russian Federation Abstract The article shows the relevance of the use of universal modular fixtures (UMF) and the approach to the design of their layouts with the using CAD-systems. Developed algorithm of design and in the formalized form described the process of design assembly UMF including operations of choice of designs of mounting, housing, clamping, guides, different, basic and fixing elements of UMF, an assessment of need of application of different elements of UMF, calculation of effort of fastening of a detail, calculations of errors of basing and fastening, check of ensuring accuracy of processing on the designed assembly UMF and creation of design documentation. The proposed algorithm can be used as a basis for the development of software for the design of assembly UMF using CAD– systems. Keywords universal modular fixtures, formalized description, design composition, the algorithm of the design process
