Method of determination of change of the shape of structural elements during heat treatment by results of measurement of his geometry

摘要

During heat treatment of products and in various technological processes connected to influence of intensive thermal fluxes, the deviation of the shape is probably inadmissible. The reason of distortion for non-uniformity of processing at technological process is the formation of non-elastic strains of inadmissible values and others. The aim of the present work is the development of methods of an estimation of a deviation of the shape on the basis of measurement of geometry of a product before and after of temperature, technological or force influence. The necessity of work is caused by that the direct measurement of coordinates of points of a surface of products with the help of measuring installation does not allow to give the conclusion about a deviation of the shape of a product owing to complexities in comparison given of account and direct measurements. It is explained to that the rule of a product before heat treatment in system of coordinates of measuring installation changes.
