Coordinate measuring machine and method for compensating for large workpiece masses
First Claim
1. A coordinate measuring machine, with a measuring system for measuring a workpiece, a carrier structure for carrying the measuring system and a base plate for supporting the workpiece, wherein the carrier structure is movably guided in at least one direction on the base plate, and wherein the coordinate measuring machine also has a first support system with at least three supports for supporting the base plate, wherein the coordinate measuring machine also has a second support system and a control device for controlling the second support system dependent on a force application to the first support system.

Abstract
The present invention relates to a coordinate measuring machine with a measuring system for measuring a workpiece, a carrier structure for carrying the measuring system and a base plate for supporting the workpiece. The carrier structure is movably guided in at least one direction on the base plate. The coordinate measuring machine also has a first support system with at least three supports for supporting the base plate, a second support system and a control device for controlling the second support system dependent on a force application to the first support system. The present invention also relates to a method for compensating for large workpiece masses on a coordinate measuring machine.

23. A method for compensating for large workpiece masses on a coordinate measuring machine with a measuring system for measuring a workpiece, a carrier structure for carrying the measuring system and a base plate for supporting the workpiece, wherein the carrier structure is movably guided in at least one direction on the base plate, and wherein the coordinate measuring machine also has a first support system with at least three supports for supporting the base plate, a second support system and a control device for controlling the second support system dependent on a force application to the first support system, comprising the following steps:
-
calibrating a reference state of the base plate by means of the first support system, arranging on the base plate a workpiece to be measured by means of the coordinate measuring machine, determining variables that represent the forces applied to the at least three supports of the first support system by the workpiece, and controlling the second support system by means of the control device in such a way that the reference state is restored. - View Dependent Claims (24)
