Abstract
The paper describes a method of accuracy improvement for multi-axis NC-controlled technological and measurement systems. Such systems are essentially cyber-physical in conditions of integration of calculations into physical processes in modern digital production. Volumetric accuracy – ability of a system to precisely reproduce a complex geometrical surface – is an important characteristic of multi-axis systems. Both measurement devices and methods of error correction are being improved by up-to-date researchers. The paper considers a method of convenient visualization of large amounts of collected data and an approach to improve volumetric accuracy by means of volumetric error compensation. The considered visualization method provides valuable data on multi-axis system’s accuracy characteristics and information about infl uence of various error components on multi-axis system’s error map. The accuracy improvement approach was implemented by original software. The experiments confi rmed accuracy improvement and low time and material costs of the method. The proposed method and approach are basis for consolidation of accuracy information collected from various multi-axis systems into united enterprise network and offers possibilities for artifi cial intelligence employment in order to develop new and advance existing technologies.
