A very popular version of the coordinate measuring machine (CMM) is the portable CMM “arm,” not to be confused with the “robotic arm” or simply, robot—as it is called in the factory automation world. Robots are motorized, machine-driven devices that have tube segments connected by articulating joints. The portable CMM (PCMM) arm is not motorized but manually operated. The lack of motors is part of what makes them especially portable, lightweight, adaptable, and versatile.

Unlike robots and CNC CMMs, portable CMM arms don’t require programming. However, digital work instructions are often employed with PCMM arms to make them more productive, controlled, and repeatable. CMM arm accessories are an essential part of the everyday use of these systems, and employing the best and most appropriate add-ons will make the job go faster and easier. These accessories are used with CMM arms manufactured or sold by API, Hexagon, FARO, Kreon, LK, Master3DGage, Nikon, Romer, Tomileri, and Trimos.
