Abstract
In the area of mechanical engineering, rotating components are not always nominally cylindrical. Sometimes, we also deal with rotating parts with variable diameters. Examples of such parts are rolling elements of bearings shaped like barrels or cones. In industrial practice, rotating components with tight dimensional tolerances are usually measured with the so-called radius-change measuring instruments. The analysis of the measurement of nominally noncylindrical elements showed that the nonlinear characteristics of the measuring sensor have a significant impact on the measurement accuracy. Taking this into account, the authors developed the concept of compensation of the nonlinear characteristics of the sensor in radius-change measuring instruments. The work contains a theoretical description of the concept developed and the results of its experimental verification.
期刊介绍:
Precision Engineering - Journal of the International Societies for Precision Engineering and Nanotechnology is devoted to the multidisciplinary study and practice of high accuracy engineering, metrology, and manufacturing. The journal takes an integrated approach to all subjects related to research, design, manufacture, performance validation, and application of high precision machines, instruments, and components, including fundamental and applied research and development in manufacturing processes, fabrication technology, and advanced measurement science. The scope includes precision-engineered systems and supporting metrology over the full range of length scales, from atom-based nanotechnology and advanced lithographic technology to large-scale systems, including optical and radio telescopes and macrometrology.
