Abstract
This paper describes estimation and evaluation of volumetric errors of machine tools based on the multi-lateration principle. The principle of multi-lateration is to determine the target location by measurement of distances from three points. The measuring method in this paper is for quicker, low-cost evaluation of volumetric errors by using only a laser interferometer. We evaluate its estimation accuracy by experiments and simulation. To simplify the problem, this paper focuses on the two-dimensional measurement of the target position.
Keywords: Volumetric errors, Laser tracker, multi-lateration, Estimation accuracy.
