Surface touching method e.g. for component, involves shifting probe relative to component mounting plate in such manner that point with surface of component at contact position steps into contact and rests against first contacting force

摘要

The method involves shifting a probe relative to a component mounting plate in such a manner, that a point with the surface of the component at a contact position (47) steps into contact and rests against a first contacting force. A determination is made for a first coordinate (x1) of the probe in a coordinate system (10) of a coordinate measuring apparatus. The probe is shifted relative to the component mounting plate whilst maintaining the contact of the point with the surface at the contact position and the point rests against the surface with a second contacting force (F4). The probe is shifted relative to the component mounting plate maintaining the contact of the point with the surface at the contact position moved in such a manner, that the point rests against the surface with a third contacting force (F1). A determination is made for a second coordinate (x7) of the probe in the first coordinate system of the coordinate measuring apparatus. The second contacting force is larger or smaller than the first contacting force (F1) and the third contacting force (F7). A coordinate (x0) of the surface of the component is determined at the contact position in a second coordinate system as a function of the first coordinate and the second coordinate (x7) of the probe. An independent claim is included for a coordinate measuring apparatus and a computer-readable medium.
