CMM Inspection

Have you ever heard of CMM Inspection?

For decades, companies requiring high-precision measurements have often turned to CMM (Coordinate Measuring Machine) inspection programming software, a technique that offers a state-of-the-art solution for offline programming that reduces programming time and ensures rapid response to design changes. This offers an optimization of the entire program development process that sharpens feature definition and routing through to program generation and validation. It is a crucial step in monitoring production quality and ensuring that large parts meet design specifications for use in critical applications. CMMs are most often used to test a part or assembly to determine whether or not it respects the original design intent.

The advantages of using CMMs are: accuracy, speed and reduced human error. These machines are capable of delivering incredible sub-millimeter accuracy on a wide variety of geometries.

There are several different types of CMMs. Generally, CMMs are classified according to their structures, we will name a few:

- Bridge CMM: features a probing system that moves along three axes: X, Y and Z. Each axis has a sensor that helps monitor the position of the probe as it moves along what you want to inspect, and these detect points on the surface of the object. These points end up forming a "watertight mesh" which is what the digitization of the object shows us.

- Gantry CMMs: these are typically much larger than bridge CMMs as they are designed to eliminate the need to lift a part over a high surface. They also offer levels of accuracy, but for very heavy or very large parts.

- Optical CMM: These are portable non-contact devices. They use an arm-free system with optical triangulation methods to scan and acquire 3D measurements of objects. Thanks to their advanced image processing technology, this technique is ultra-fast and they guarantee metrology-grade accuracy.

- Among other techniques...

The most commonly used technique in the case of large and heavy objects such as those manufactured at Serviacero ORBIS is optical CMM. Each object has its different CMM technique applied, it all depends on the results you want to see after finishing the process. Its advantages are that it is portable and lightweight, its measurement volume is expandable, acquisition times are very fast, it is very easy to operate and does not require rigid assemblies.

CMM analysis is an added value and very important for Serviacero ORBIS because through it we ensure the tolerances and more specific requirements of the customer generating an excellent buying experience, with this we promote long-term relationships with the customer.
