A STUDY OF THE APPLICATION OF VOLUMETRIC COMPENSATION BY DIRECT AND INDIRECT MEASUREMENT METHODS

Abstract

The present article deals with the measurement methods based on experimental tests and their impact on the resultant volumetric error of CNC machine tools (MT). Volumetric error compensations represent a promising technology to increase the production accuracy of machine tools. This article studies direct and indirect methods to measure the volumetric accuracy on a MT. The assessed parameters are not only the resultant volumetric error of the machine, but also time consumption of measurement, repeatability, and evaluation of individual geometric errors. Finally, recommendations are made to improve the effect of volumetric errors compensation using the above-mentioned methods for three-axis MT.
