Robotic Machining-Aerostrcture
Project Scope
- Automatic drilling of 8000 holes with countersink (CSK) for an 8-meter-long aerostructure.
- Automatic trimming of 6-meter-long aerostructure.
- Meet drill hole size with a 30-micron tolerance.
- Meet +/- 400 microns hole position accuracy.
- Each hole must be drilled with CSK within 28 seconds.
- Maintain Flushness within 50 microns.
- Ensure Normality within one degree.
Business Challenges
- High-precision operation.
- Ensuring High quality and consistency.
- Difficult for manual labor.
- Safety concern.
- Production efficiency.
ARi’s Solutions
- ARi designed and built a cutting-edge turnkey solution, the first in Asia, for automated robotic machining for aerostructure assembly.
- The system includes End of Arm Tooling (EOAT) mounted on a Kuka Robot, which was then installed on a 14-meter-long Rail/Robot Slider.
- The entire machining cell has 2no’s of KUKA robots, each equipped with EOAT mounted on separate rails/robot slider installed on both the LH & RH sides of the aerostructure component, working in tandem.
- The robotic machine cell has a total of 20 axes, all integrated and controlled by Siemens 840D CNC system.
- The system achieves 15-20 microns accuracy in all the axes.
- Drilling and CSK of each hole are done within 28 seconds.
- Flushness of less than 50 microns and normalcy of less than 1°(degrees).
- Executing smart manufacturing with smart automation.
