A method for identifying a geometric error of a multiaxial machine tool and a multi-axle a machine tool

摘要

A method for identifying a geometric error of a multiaxial machine tool has a measurement step for indexing a position of a target ball, which is either to a main spindle (11) or a table (6) is made, in many angles about an axis of rotation, and for measuring the position of the target sphere on respective indexed positions with the use of a contact probe, which on the other component of the main spindle (11) and the table (6) is mounted, a step for calculating a geometric error, a geometric errors from the measured position of the target ball to calculate, a step (s1) for calculating an ellipse facilitate pressure, in order to obtain a ellipses approaches from pressure through an arc track which is measured by actuation of the axis of rotation, and a step (s3 to s6) for correcting an error, in order to obtain a scaling errors of translation axes from the calculated ellipses vicinity of pressure to calculate and to correct.
