The influence of manufacturing errors of cases on their assembly

Abstract

Abstract The authors of the article propose a way to increase the accuracy of processing pipe casings included in special products. Currently, in the current production of these products, there is a need to increase the accuracy of manufacturing cases, so it was decided to conduct research work. The article discusses the process of processing long bodies from thick-walled workpieces using hoods, which ensures high precision workpieces and minimal impact on the properties of the initial type of workpiece. As a result of the research, the significance of the geometric errors of the component pipes of the product on its functionality is analyzed. The achieved accuracy of the manufacture of base surfaces and the parameters of their possible distribution are shown. The similarity of the parameters of the initial part and further assembly is determined, it is also shown that the runout of the end surfaces of the part has a significant effect. The optimal basing scheme for finishing the end surfaces of long bodies is shown.
