CNC (computer numerical control) cutting technology which was added to plasma tables in the early 1990s gave the user more flexibility, allowing for more cut diversity and ease in creating new shapes “on demand.” Modern tables allow a worker to make a set of instructions, programmed directly into the machine (computer), with highly intricate detail that will produce smooth-edged cuts in a fraction of the time of yesteryears. Thus the potential for “mass production” was started with plasma. This generally made these early machines dedicated to making simple and repeatable patterns. ![]() Plasma tables, back then, were extremely expensive, heavy, and quite slow. ![]() Traditional early plasma cutting created a lot of metal chips, produced jagged edges, and lacked the accuracy of modern CNC plasma systems.
