An Online Simultaneous Measurement of the Dual-Axis Straightness Error for Machine Tools
Vertical straightness errors are the key factor that affects the flatness of the workpiece during vertical machining. Traditionally, the individually measured and fitted vertical straightness errors of the <i>X</i> and <i>Y</i> axes are used to compensate the <i>Z</i...

Traditionally, the individually measured and fitted vertical straightness errors of the <i>X</i> and <i>Y</i> axes are used to compensate the <i>Z</i> axis and, thus, obtain the flatness of the working table of the machine tool. However, it is difficult to measure and compensate the vertical straightness error of the desired position on the working table, not to mention the centroid variation effect of the working table on the measured data. In this study, an online dual-axis measurement system with repeatability (3σ) of 2.46 μm is developed to simultaneously measure <i>X</i>-axis and <i>Y</i>-axis straightness errors of the desired position of a working table. Furthermore, the measured data are utilized to establish a flatness error model to reduce the vertical straightness error of the working table such that the repeatability (3σ) of the measured flatness may be kept within a range of 0.65 μm.https://www.mdpi.com/2076-3417/8/11/2130dual-axisvertical straightnessflatness error modelmachine tools |

Vertical straightness errors are the key factor that affects the flatness of the workpiece during vertical machining. Traditionally, the individually measured and fitted vertical straightness errors of the <i>X</i> and <i>Y</i> axes are used to compensate the <i>Z</i> axis and, thus, obtain the flatness of the working table of the machine tool. However, it is difficult to measure and compensate the vertical straightness error of the desired position on the working table, not to mention the centroid variation effect of the working table on the measured data. In this study, an online dual-axis measurement system with repeatability (3σ) of 2.46 μm is developed to simultaneously measure <i>X</i>-axis and <i>Y</i>-axis straightness errors of the desired position of a working table. Furthermore, the measured data are utilized to establish a flatness error model to reduce the vertical straightness error of the working table such that the repeatability (3σ) of the measured flatness may be kept within a range of 0.65 μm. |
