Static deformation of precision machine tools for large scale aspheric components manufacure

摘要

Large scale aspherical optical component plays an important role in National defense industry. It is based on the large size aspherical machine tools, so the stiffness and accuracy of the machine tools lead to the accuracy of the mirror directly. The tools consist of a turntable shaft and three linear axes including X/Y/Z axises. This paper analyzes a desirable arrangement of Y-axis linear motors so that the error of Y-axis produced indirectly can be minimized.
