One of the problems of machine building is the definition and measurement of the geometric shape of large-sized parts of machines and mechanisms, which are often the bodies of rotation. Similar parts are used with high intensity in the drum type connections. Therefore, diagnostics of parts is required to determine the possibility of their further use. One of the criteria for this is the shape of the surface of the part and its deviation from the normative values. In the framework of this article, a method for estimating the shape of large-sized bodies of revolution considered which makes it possible to perform measurements with high accuracy for parts of arbitrarily large dimensions

Keywords: large items, large rings, deviations from roundness, body rotation
