When it comes to accurate, speedy, and precise measurement of parts there is nothing better than a Coordinate Measuring Machine
. These devices utilize a physical probe (although some come equipped with laser scanners) to create a 3d representation of the object being scanned. Intended for use in a variety of applications CMMs provide a great advantage over part measurement performed by hand.
Whether reverse engineering a part by generating a 3d CAD model or analyzing a portion of an assembly for manufacturing flaws, CMMs have revolutionized the world of accurate physical measurement. Being able to either generate a precise software representation of the object scanner or being able to compare it against an existing map to check for deviations from spec, CMMs are able to significantly increase the quality of part production in all sorts of manufacturing industries.
With new data processing advances and various miniaturization advances along with various design improvements have bought about a revolution in CMM technology. One of the newer segments of CMM technology is in portable CMMs. Being much lighter and more maneuverable than ordinary CMMs they are finding use in various manufacturing operations around the world.
A great advantage of a portable CMM is just that its portability. Ordinarily large CMMs needed their own designated area for which to perform accurate measurements. Advances in sensory technology have enabled the production of portable CMM systems that are able to be moved from location to location without needing to be recalibrated and certified. This has made it easy to accurately measure and graph the structure of large and/or heavy objects when moving those objects would not be possible or cost-effective.
Portable CMM systems have also found an enhanced use in the automotive parts manufacturing industry. These portable CMM arms are able to accurately measure parts to check if they meet the exacting specifications and tolerances required for the construction of automobile-related parts and assemblies. This has greatly sped up and improved the efficiency of quality control in these part fabrication plants.
