Technological inheritability of product properties at the development and production stage of its Life Cycle

Abstract

The relationships of technological providing of standart quality parameters of products with the substages and stages of their Life Cycles is analyzed. The prognostic nature of the relationships between the functional properties of the product and the technology of their providing requires thorough theoretical and experimental research for the modern mechanical manufacturing. The priority of information support of modern mechanical engineeering production in the conditions of self-organization of technical systems at designing of technological processes of products manufacturing is noted. The general laws of evolution of technical systems are formed on the basis of system functional, morphological, informational analysis by studying the relationships and interactions of functional, morphological and informational description. The actuality of the study of the processes of damage accumulation and material degradation for the characteristic types of products destruction is argued. The expediency of a synergetic approach in the analysis of technical objects and technological systems is established.The goal of this research is to develop a principal scheme for the formation of quality parameters of part with predict of the probability of its failure in manufacturing, taking into account the technological inheritability of properties. The basic scheme of formation of products quality parameters taking into account all substages of development and production stage of its Life Cycle is developed. The mathematical model for predicting the probability of non-defect production P (t) of products suitable for further operation, taking into account technological inheritability, is proposed. Further research is related to the optimization of design and technological solutions and the structure of technological processes, taking into account the technological inheritability with a rational combination of blanking, intermediate, finishing and final-strengthening operations.
