Aerospace Heat Exchanger Form and Flatness Inspection Using Non-Contact Optical Metrology
Executive Summary
As the demand for higher performance heat exchangers continues to increase across various high-tech industries, the geometry of these components becomes more intricate. New generations of thermal management devices now incorporate more complex and tightly spaced cooling fins to maximize performance within reduced physical space. Traditional tactile measurement tools face limitations in measuring such components without causing damage. Non-contact 3D optical metrology, however, offers a reliable and damage-free inspection method.
Overview of 3D Metrology Capabilities
EDM Intelligent Solutions uses cutting-edge non-contact 3D metrology equipment to measure components with highly complex geometries. Our robotic and 5-axis systems can quickly and accurately evaluate height, flatness, and pitch, ensuring quality and performance conformance for demanding applications.
Key capabilities include:
- Form and height measurement of intricate features
- Flatness evaluation of complex surfaces
- Pitch and spacing measurement for densely packed fin arrays
- Non-destructive, automated inspection processes
Application Case Study: Heat Exchanger Inspection
Component Overview
- Type: High Performance Heat Exchanger
- Material: Stainless Steel
- Industry Use: Aerospace, Medical, Defense, Scientific, and more
Inspection Process
The component in this study, a high-performance stainless steel heat exchanger, required detailed inspection to confirm critical features such as fin height, flatness, and pitch. Due to the complex geometry and tight spacing between the fins, traditional tactile CMMs posed a risk of damaging the part or failing to capture accurate measurements.
Instead, the team utilized the RSH-M10 Robotic 3D Metrology System to perform a non-contact scan of the component. The system collected precise height and flatness data across the entire fin surface area. For added capability, the part could also be inspected using the Advanced 5-Axis CNC MVi5 3D Metrology Center, which provides flexibility and high-resolution measurements in complex orientations.
