NDT-RAM™ is the Ideal for Powdered Metal Part Testing

Cincinnati, OH. - (12/18/02) THE MODAL SHOP, INC. announces the enhanced functionality of the Non-Destructive Testing using the Resonant Acoustic Method (NDT-RAM)™ application, based on its SDC003 LanSharc™ hardware platform. The system uses an instrumented impact hammer and a microphone for quality assurance testing of powdered metals and castings via the acoustic signature of components in a quick, cost-effective manner. The system allows for fully automated quality control testing of 100% of parts in a production environment.

With no part preparation required, this technique can successfully identify internal and external flaws due to dimensions, voids, cracks, material density, bonding and manufacturing processes. The NDT-RAM series of products includes products for both production and engineering development applications, ranging from manual to the fully automated.

The NDT-AUTO configuration is fully automated, and includes an industrially packaged, 24 bit, 50 kHz LanSharc as the analysis core, with an electrically controlled impact hammer and ICP® microphone as sensors. Additionally, the system includes a production line conveyor system with an acoustic chamber, photoelectric eyes, PLC, encoder and industrial PC with flat panel touch screen.

The manual NDT-MAN configuration is ideal for mobile spot-checking and/or troubleshooting, and is extremely rugged and portable using just the LanSharc digital controller, an impact hammer and a response microphone with a laptop PC.

The NDT-RAM system is ideal for manufacturers or users of metal parts that have substantial inspection cost, require 100% inspection, produce or use safety-critical parts, have substantial scrap costs due to false rejects, or simply want to improve their part quality. It can be used for the inspection of parts used in a variety of industries, including automobiles, aircraft, consumer goods, medical devices and other metallic products.

The system is portable, no part preparation is required, parts are fully inspected in seconds, and scrap costs are reduced by the elimination of false rejects. The software application is user-friendly, and allows for report generation – including statistical analysis. The same system can be used for the contact-or non-contact testing of many different parts.

NDT-RAM utilizes the LanSharc Smart™ Digital Controller, a highly programmable and configurable platform for advanced machine process vibration applications development and deployment. The LanSharc is designed for applications that monitor critical part quality or protect critical process machinery and systems from either failure or degradation. As such, it combines the latest in analog to digital conversion and digital signal processing technology with abundant memory and communications resources. In addition to the NDT-RAM application, THE MODAL SHOP INC. also offers the ePIG™ system for affordable, non-intrusive part quality and process monitoring on single spindle transfer line applications, and the BEAR™ system for machinery health maintenance of basic rotating machinery.
