CMM (Coordinate Measuring Machine)

CMM for Defense Industry

Key Takeaways

  • Defense industry applications require CMMs that balance high-precision stability for manufacturing with the flexibility needed for dynamic maintenance and MRO tasks.
  • Model selection should be based on specific operational needs: gantry/bridge for high-tolerance production, and portable/arm units for on-site, versatile inspections.
  • Advanced software is essential for defense metrology, providing environmental compensation, CAD comparison, and automated reporting to ensure compliance and efficiency.
  • User-friendly, portable CMM systems reduce training barriers and inspection time, allowing technicians to perform complex geometric measurements across diverse defense environments.

Coordinate measuring machines, also known as CMMs, are measuring devices that collect geometric data based on coordinate points taken by a contact probe. Known for their efficiency and accuracy, CMMs are integrated into industries like aerospace, automotive, and defense.

Like other measuring and inspecting tools, there are multiple models and software to consider when purchasing a coordinate measuring machine. If you’re in the defense industry and weighing your CMM options, keep reading to learn how to make an informed decision.

How is the Government Utilizing CMM Machines?

In order to make sure parts for an airplane fit up correctly, the parts need to be inspected to ensure they're up to standard before installation.

When purchasing a CMM, there are four models to choose from: bridge/gantry, horizontal, cantilever, and arm. All of these models use a probe to take measurements.

Additionally, a lot of CMMs are automated nowadays and can import/export CAD models, so purchasing your desired CMM machine model also means considering what software you need. Let’s explore how to choose a CMM for defense.

Choosing the Right CMM for Government Defense Application

Select the Proper Model and Software

Deciding on your model and software includes considerations like how skilled your technicians are, your measurement tolerance, where you’re measuring or inspecting, and the type of components you work with.

Model

Gantry and bridge CMMs are popular in government applications because of their tight tolerance and stability. Because of their stable and accurate workability, these models are best for manufacturing and in-depth maintenance of defense equipment.

Cantilever and horizontal CMMs are not as accurate as gantry or bridge, but they still fit the industry’s tolerance. They have an ease of use that is helpful for quick measurements or general maintenance.

Arm and portable CMMs are the most flexible type of CMM because the probe can be used on the shop floor and goes where you need it to, when you need it to. As a dynamic industry with competing priorities, arm and portable CMMs work well for defense metrology solutions because of the flexibility for measuring and inspecting parts.

Software

Software is the middleman between you and the CMM.

Defense inspection and measurement applications are complex. Including software that calculates dimensions, creates reports, and analyzes data will improve your efficiency and accuracy.

Environmental control software that standardizes the environment is another beneficial software. Temperatures and contaminants affect dimensions, so this software calculates what the dimension would be with a neutral environment so you don’t have to.

Overall, software that is user-friendly and intuitive makes a world of difference when using a CMM. User-friendly software cuts down measurement and inspection time significantly and allows more technicians into the process even without extensive training.

Integrating the CMM into Defense Manufacturing

A CMM can check the contour of complex geometries, such as turbine blades, to ensure that parts for the aerospace and defense sector are manufactured to the highest quality standard.

If you are measuring or inspecting in the defense industry, you need a CMM with accuracy and flexibility to keep up with changing priorities. That’s why we offer handheld and portable CMMs that can meet defense industry demands.
