Integrated metrology system
Motivation
The in-process and final measurement of a workpiece of approx. 1m3 or larger takes a large amount of time during transport and handling to the measuring centre or eventually back to the machine for repair.
The task is to minimize these production losses.
Description
Integration of a metrology system (3D coordinate measuring machine) with a touch probe into the machine tool, enables precise measurement of workpieces directly on the machine. Own machine errors are eliminated by the use of an independent measuring device - an external "Leica" laser measuring system.
During measurement, the machine tool is controlled in the same way as a 3D coordinate measuring machine. The system also allows the measured errors to be automatically transferred to the machine tool control system as a correction to the CNC program (the machine can eliminate machined errors without the need to change the NC program).
Benefits
- Significant time saving (no need to transport the workpiece to the measuring machine and back)
- The machine tool is controlled directly from the metrology software - simple to operate
- Elimination of own machine errors
- Correction of errors/inaccuracies on the workpiece without changing of the NC program
