Dynamic path correction in robotic machining
Customer name :
Fives
Completion date : 2021-2023
In brief
Development of a method for dynamic correction of robotic trajectories for drilling and contouring, enabling precision to meet industrial requirements despite the mechanical limitations of the robots.
Project summary
The aim of this project was to improve the machining precision of industrial robots by compensating for trajectory errors in real time. The team studied structural deformations, mechanical clearances and dynamic deviations to design an optimization strategy capable of adjusting the tool position during movement. Trials under representative production conditions (drilling and contouring) validated the method, guaranteeing machining quality equivalent to that of conventional machine tools.
CTA's role
CTA led the robotic performance analysis, developed the dynamic correction algorithms, programmed and executed the machining tests, then documented the method for transfer to the industrial environment.
Results
- Measurable improvement in machining precision for drilling and contouring.
- Reduce non-conformities and rework.
- Validation of a reproducible dynamic correction approach that can be integrated into other robotic cells.
