The evaluation of aerostatic guide-ways for planar XY stage
평면 XY 스테이지용 공기베어링 안내면 오차 평가
Abstract
This paper describes estimation method for 2D position error of planar XY stage from measured profiles of guide-ways. The XY stage usually moves along its guide ways. The motion error of each stage has effect on 2D position errors of XY stages and affected mainly by profiles of guide-ways. To estimate 2D position error and flatness of stages, the profiles of guide-ways were measured and used in motion error estimation.
