Device and method for determining the position of a working part
First Claim
1. A system for determining the position of a working part of a tool on a machine comprising:
- a position-determining apparatus comprising;
at least one detector placed generally at a designated place on said machine spaced away from said working part of the tool, wherein said position-determining apparatus is configured to provide data corresponding to the position and orientation of said designated place on said machine in a fixed coordinate system;
at least one position relationship device configured to determine a positional relationship of said working part of said tool relative to said designated place on said machine in a machine-based coordinate system;
a calculating device resident on said machine configured to provide at least one of the position and the orientation and inclination of said working part of said tool in said fixed coordinate system based upon the position and orientation of said designated place on said machine in a fixed coordinate system and said positional relationship of said working part of said tool relative to said designated place on said machine in said machine-based coordinate system; and
a geodesic instrument with a target-seeking function for measuring the position of at least one target placed on said machine, wherein said geodesic instrument is placed at a distance from said machine from which said at least one target is easily visible from said geodesic instrument.

Abstract
A device and method for determining the position for a working part of a machine with a position-determining apparatus is disclosed. A detector is placed at a defined place on the machine to determine the position in a fixed coordinate system. A positional relationship device determines the positional relationship of the working part in relation to the detector in a machine-based coordinate system. A calculating device calculates, with signals from the position-determining apparatus and the positional relationship device, the position of the working part in the fixed coordinate system. The position-determining apparatus comprises an inclination- and orientation-measuring device that measures the instantaneous position and orientation of the position of the machine in the fixed coordinate system. The calculating device converts the measuring result from the position-determining apparatus and the positional relationship device to give the instantaneous position and orientation of the working part in the fixed coordinate system.
