Gauging difficult parts at the press brake

March 27, 2003

By:

Gone are the days when engineers and draftsmen slaved for hours over drafting boards with a pencil and slide rule in hand (does anyone remember slide rules?). Today we've moved beyond slide rules and even beyond hand-held calculators to personal computers and mainframes to do much, if not all, of our design work. CAD and CAM software has made this possible.
