ABSTRACT:
A system and method for monitoring clinched joints senses lateral displacement of die segments during formation of a joint, which depends on joint button diameter. The system determines whether a joint is acceptable by correlating acceptable button diameter with acceptable amount of punch advancement. A predetermined number of unacceptable joints indicates excessive punch and/or die wear.
