METHOD FOR MEASURING A WORK PIECE, CALIBRATION METHOD AND COORDINATE MEASURING DEVICE

摘要

The method involves sampling a point (53) of a surface (51) of a work piece (52) by a sensing device i.e. tracer pin. The sensing device exerts one of sensing forces (f') on the surface. The sensing device and the work piece are positioned and/or oriented relative to each other under consideration of the directional dependent flexibility of the sensing device, such that unintentional slipping of the sensing device on the surface or an unintentional deviation of the sensing device from an intended path to the surface does not occur, during sampling of the point of the surface. Independent claims are also included for the following: (1) a method for determining a direction dependent flexibility of the sensing device (2) a co-ordination measuring device with a sensing device for sensing of a point of a surface of the work-piece.
