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 equipment placed generally at a designated place on the machine spaced away from the working part of the tool, the position-determining apparatus configured to provide data that corresponds to the position and orientation of the designated place on the machine in a fixed coordinate system;
at least one position relationship device configured to determine a positional relationship of the working part of the tool relative to the designated place on the machine in a machine-based coordinate system;
a calculating device resident on the machine configured to provide at least one of the position and the orientation and inclination of the working part of the tool in the fixed coordinate system based upon the position and orientation of the designated place on the machine in a fixed coordinate system and the positional relationship of the working part of the tool relative to the designated place on the machine in the machine-based coordinate system, wherein said calculating device uses earlier calculation results to calculate a probable position, orientation, direction of work and speed a certain time in advance for the working part of the tool.

Abstract
The invention relates to a device and to a method for determining the position for a working part of a tool on a working machine with a position-determining apparatus (2, 4, 5, 6; 2, 4a, 4b, 5, 6′; 31, 33, 49, 50, 51, 1′,53). At least one detector equipment (4, 5, 6; 4a, 4b, 5, 6′; 31, 33; 49, 50, 51, 53) is placed at a defined place on the working machine (3; 52) in order to determine the position of this position in a fixed coordinate system. At least one positional relationship device (11) determines the positional relation of the working part in relation to the detector equipment in a machine-based coordinate system. A calculating device (20) 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 (5, 20; 4a, 4b, 20; 31, 20; 51, 20) so that the apparatus measures both the instantaneous position and orientation of said position of the working machine in the fixed coordinate system. The calculating device (20) converts the measuring result from the position-determining apparatus and the positional relationship device in order to give the instantaneous position and/or orientation of the working part in the fixed coordinate system.

16. A method for determining the position of a working part of a tool on a machine comprising:
-
measuring both a position and an orientation of a designated place on the machine spaced away from the working part of the tool and in a fixed coordinate system;
determining a positional relationship of the working part of the tool relative to the designated place in a machine-based coordinate system; and
calculating in the fixed coordinate system, at least one of an instantaneous position of the working part of the tool and an instantaneous orientation and inclination of the working part of the tool based upon the measured position and orientation of the designated place on the machine and the positional relationship of the working part of the tool relative to the designated place on the machine and, with the help of earlier calculation results, a probable position, orientation, working direction and speed a certain time in advance for the working part of the tool. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
