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.
