Burrs on parts worldwide cost an estimated 27 billion dollars to 50 billion dollars annually, not including lost revenue from rejected parts. Despite that high cost, parts manufacturers typically only have a superficial understanding of burr economics. Few are aware that there are at least 109 different deburring processes to choose from as well as a variety of burr prevention techniques. Roughly 73,000 workers in the U.S. perform full-time deburring while almost 1 million machinists and toolmakers who cut metal or plastics also perform some deburring or deflashing. Practically everyone who works in a machine shop is familiar to some extent with burrs. Few enjoy removing industry's little thorns.
