CGI's Spec.Check inspection software, for use with any digitizing system, is designed for first article inspection or mold qualification and can save users time in performing dimension measurements - up to 75 percent, according to the developer. In...
-
First article inspection is an essential and crucial step in product development and in proving a new mold. But when the part geometry is complex – and especially when the internal geometry is complex – the measuring and qualifying process can take days...
