Gantry Type 공작기계의 CROSS RAIL 처짐량 측정 및 분석

This study of purpose is to predict and to compensate displacement of Cross Rail of Gantry type when Spindle Head is moving on Y-axis anywhere. For composition of experiment is Mahr probe, Mahr Millitron 1240, A/D converter. As moving 500kg of mass block, measure displacement and compare with analytical result which load is acting on Y-axis at certain location so we show method of compensation and it is possible and efficient one of others. The analysis is carried out by FEA simulation using ANSYS also we induce equation.
