The Role of Metrology in the Aerospace Industry

The aerospace sector stands at the forefront of engineering excellence, where the boundaries of technology and precision are continually pushed to ensure safety, performance and innovation. In this high-stakes field, metrology plays a pivotal role, and EDM Intelligent Solutions delivers high-performance systems to meet measurement needs in the sector.

Understanding Metrology

Metrology is the science of measurement and is used to standardize units of measurement worldwide. This standardization also supports correctness in measurement, ensuring precise guidance and engineering validation for components in the aerospace industry.

Historically, metrology has been associated with simple tools like calipers and micrometers, but technology continues to advance in this area to improve measurement precision. One of the key players in metrology in recent decades is the coordinate measuring machine (CMM). CMMs have laid the foundation for further advancements in measurement technology led by EDM Intelligent Solutions. Our systems use advanced 3D technology to deliver precision optical inspection and dimensional metrology to meet tight tolerances in the aerospace industry and beyond.

The Importance of Metrology in Aerospace Engineering

In an industry where the margin for error is virtually nonexistent, metrology ensures that every component is produced and assembled to the highest standards of precision. Metrology is used in aerospace engineering to guarantee:

• Safety: Metrology ensures that critical components, such as components for jet engines, are precisely measured, verified and aligned, reducing the risk of failures that could lead to severe safety incidents.
• Performance: Metrology optimizes aircraft performance by ensuring components meet the necessary tolerances. High precision in measurement guarantees that parts fit and function as designed, leading to improved aerodynamic performance, fuel efficiency and overall operational reliability.
• Efficiency: Precise measurements provided by 3D metrology in aerospace components streamline manufacturing processes. By ensuring that each part is produced accurately the first time, metrology reduces the need for rework and minimizes material waste.
• Compliance: The aerospace industry is heavily regulated, with strict standards set by governing bodies like the Federal Aviation Administration and the European Union Aviation Safety Agency. Metrology ensures compliance with these stringent regulations by providing the accurate and reliable measurements needed to meet certification requirements.

Applications of Metrology for Aerospace Technology

Metrology finds its application at every stage of aerospace manufacturing, from initial design through final assembly and even in ongoing maintenance and research. Here are several key applications:

• Design and prototyping: During the initial stages, precise metrology tools and 3D metrology centers can help operations develop prototypes that align with initial designs. These models can compare 3D scans of prototypes to 3D CAD models to uncover areas where production affected a component’s accuracy.
• Machining and assembly: As components move to production, sophisticated metrology systems, such as instruments with robotic capabilities, can ensure that each piece is manufactured within the required tolerances.
• Quality control and inspection: Metrology is critical in quality control, employing both contact and noncontact measurement techniques to inspect aerospace components. Advanced methods like 3D X-ray tomography and ultrasonic testing may help detect internal defects that could lead to failures in critical applications.
