- Abstract
The geometric error of machine tools can usually be reduced or compensated by various methods, but the influence of encoder performance on machining quality is often ignored. The purpose of this work is to analyze the influence of micro-cyclic error in linear encoders on milling surfaces and establish a compensation method to eliminate the encoder error. First, the origin of the micro-cyclic error of the linear encoder is analyzed. The micro-cyclic errors of the horizontal linear axes of an ultraprecision machine tool are preliminarily measured. The errors are also identified through milling tests. Second, a surface topography model for milling surfaces is established with consideration of the encoder micro-cyclic error. Based on the established model, a compensation method for the encoder micro-cyclic error is proposed. Finally, the error distribution model is validated by diamond ball-end milling experiments. Further experimental results confirm that the proposed compensation method can effectively remove the encoder error-related stripes from machined surfaces. The surface quality is considerably improved.
