It is not an abbreviation for anything. Here is the history: Originally, OMAX started out as "Auburn Machine Tool", since it was headquartered in Auburn WA, and we thought that sounded like a legit machine-tool like name for a company just starting out. Few liked that name, though. It was either Earl Seekins, the manager at the time, or possibly Sandra McLain (marketing), or both who proposed "Olsen Machine and Control Systems" as a new name, to become "OMACS". Then the "CS" was abbreviated with an "X" because that just seemed cooler, to become "OMAX". We all liked that name because it was short, could be easily cut with our machines, and also could be used like a verb as in "Why don't you OMAX that part?". We felt this was a good way to promote things sort of like how the company "Xerox" could be used as a verb to make copies by "Xeroxing them".
There isn't one. Unless you count OMAX as the abbreviation of OMAX corporation.
