Assurance of Quality Indices of Technological Processes of Form-Shaping During Preproduction Stage

Abstract

Quality indices of technological processes of form-shaping in general and of machining, in particular, determine to a large extent the competitiveness of these processes and play an essential role in assuring environmental and industrial safety. The most important quality indices of these technological processes are the indices characterizing vibrations and associated noise during the implementation of technological processes. Besides, from the point of view of safety, the issues related to the rational selection of LCTA are of considerable importance. To improve the safety of technological processes, these issues must be solved as early as at the preproduction stage. The issues of improving environmental and industrial safety of technological processes of form-shaping basing on the analysis of vibrations propagation, vibrations prediction, and also the methodology for rational selection of LCTA are discussed in the article. The mathematical models of propagation of vibrations in the structural components of the equipment were developed, and the problems of applying these models for the prediction of vibration levels at a preproduction stage are discussed. The issues of creating a comprehensive criterion for LCTA selection are considered, being a tool for rational selection of LCTA and of the systems for LCTA application. The developed information retrieval system "ECO LCTA" is presented, which includes the database and ensures rational selection of LCTA.
