Program Implementation for Quality Assessment Modelof the Stamped Sheet Part Manufacturing

Abstract

Based on the criticalityanalysis, a mathematical model to assess the quality of sheet parts from titanium alloys is developed, the features of qualityassessment of the manufacture of thin -walled and high -precision parts from titanium alloys are considered. The assessment is comprehensive, consisting of 14 indicators of criticality, united in a special set. Each of these indicators characterizes the degree of meeting of a certain technical requirement. The article discusses the features of qualityassessment of the manufacture of thin-walled and high-precision parts from titanium alloys widely used in shipbuilding, aircraft industry and missile and space technique. The complexity of geometry, sizes and strict requirements for quality control at all stages of production are taken into account. The problems arising in the manufacture of such parts and the ways to solve them are described. A technological system of quality of the sheet part (CLD TS) is proposed, providing a comprehensive assessment of the conformity of products with the established regulatory requirements. Important attention is paid to the criteria for quality assessment, including geometric parameters, wall thickness, stamping accuracy and strength characteristics that affect the operational properties of the product. The methods for calculating a comprehensive assessment based on objective parameters are considered, which allow minimizing deviations from normative values. A multifaceted mathematical model has been developed, taking into account the influence of various production factors on the quality of parts. The model allows prediction of potential defects, evaluation of the resistance of parameters and identification of critical states at the manufacturing stage. The advantage of the model is the ability of integration with automated control systems, which ensures the operational adjustment of the technological process in real time. The results of the study can be used to optimize control processes, increase the accuracy and reliability of the manufacture of thin -walled parts, as well as to reduce the cost of processing expensive materials. The introduction of the developed solutions helps increasing the durability and operational safety of products, which is especially important for industries with high requirements for the quality and reliability of structures.
