The Punch Press Monitoring System is a real-time quality control and tool failure detection system using AE technology to detect very high frequency emissions that are the result of plastic deformation or material (tool, part or die) cracks. Not only does PPMS provide early detection of tool or die failure, but it also indicates the deterioration of production quality – therefore preventing catastrophic failures that could result in damage to vital components or the necessity of a major repair to the pump press. PPMS saves both time and money and increases the productivity and production quality for users, and also includes an Internet interface to allow for remote monitoring, centralized control and on-line support.
