INFLUENCE OF THE VOLUMETRIC ACCURACY OF MACHINE TOOL ON THE WORKING SPACE SIZE

Abstract

Volumetric compensation of CNC machine tools can provide a significant progress in increasing the production accuracy and hence the product quality. This paper describes the influence of the volumetric accuracy of the machine tool on the size of the working space. Impact assessment was performed on the basis of tests of three-axis vertical CNC machining center. In the practical part, the planning of the experiment according to Shainin is described, the procedure of working with measuring instruments is described and the measurement of the geometric / volumetric accuracy of the machine tool, including statistical evaluation.
