Relationship between the characteristics of machine parts and parameters of technological equipment

Abstract

The aspects of the substantion of the selection of parametera of CNC metal-cutting machines are considered on the basis of their relationship with the technical characteristics of the manufactured machine parts that make up the regional data bank. A new approach to grouping parts using cluster analysis is proposed. For the processing of eight groups of parts in the form of bodies of revolution, the parameters of machine tools are substantiated (the number and composition of shape forming coordinates, the size of the working space, the structure of technological operations, the accuracy class according to GOST 8-82E, as well as the accuracy and roughness of the processed surfaces obtained depending on workpiece material. Keywords: machine tool, numerical control, part, shape forming coordinate, workspace. v.epifanov73@mail.ru
