Spatial measurement of a workpiece that is to be produced using a machine tool, whereby measurement accuracy is improved by use of a calibration body with calibration point tangential surfaces similar to points on the workpiece

摘要

Method for spatial measurement of a workpiece (4) with a feeler (2) attached to a machine tool so that the design coordinates for a workpiece to be produced with the machine tool can be determined. Prior to measurement of the workpiece a calibration piece (1) is used and measurement of calibration points (8-10) made, the tangential planes of which (8a-10a) are essentially parallel to the tangential planes (5a-7a) of measurement points (5-7) on the workpiece. Normalized approach vectors can thus be determined. An independent claim is included for a corresponding device.
