The evolution continues with sensor and software advances
September 11, 2007 Continued improvements to CNC plasma cutting
technology have made these units much more adaptable and user
friendly. They have also helped improve consistency and cut
quality. A plasma cutting table is a workhorse in most fab
shops. The technology has seen great improvements over the
years, and it's worthwhile to take a look at its evolution. Not
coincidentally, plasma technology's growth has coincided with
technology improvements starting with the CNC. Computer numeric
control (CNC) technology was devised by a collaboration of MIT
professors and associates, and refers specifically to a computer
controller that reads G-code instructions and drives a machine
tool. The introduction of CNC machinery radically changed
manufacturing by dramatically reducing the number of steps
requiring human interaction. With the increased automation of
manufacturing processes brought on by CNC machining,
considerable improvements in consistency and qual
