MACHINE TOOL PRECISION ANALYSIS METHOD AND APPARATUS, PRECISION MEASURER, AND MACHINE TOOL MACHINING METHOD

WIPO Patent Application WO/2021/174900

A1

A machine tool machining precision analysis method and apparatus, a precision measurer, and a machine tool machining method. The machine tool machining precision analysis method comprises the following steps: obtaining multiple groups of machining deviation sets, located in multiple intersection directions, of the surface of a historical workpiece, wherein each group of machining deviation sets comprises the machining deviations of multiple points in a corresponding direction (S100); comparing the multiple groups of machining deviation sets, and identifying one, having a relatively small dispersion degree, of the multiple groups of machining deviation sets as a stable precision set (S300); and outputting a measurement direction corresponding to the stable precision set as an optimal machining direction (S500). Multiple machining deviations in the stable precision set are relatively concentrated, and it shows that the machining deviations of the workpiece in the measurement direction corresponding to the stable precision set are not greatly different, the fluctuation of the surface of the workpiece in the measurement direction corresponding to the stable precision set is small, and if the measurement direction corresponding to the stable precision set is subsequently used as a machining direction, the surface of a machined workpiece is flat, and the precision of the workpiece is high. Therefore, the machining precision is improved by analyzing historical data.
