NDT-RAM Software Upgrade Simplifies Metal Component Part Inspection

The Modal Shop has released new software to aid in the process of nondestructive resonant inspection for large and small metal components.  NDT-RAM™ Software Version 7.0 is a powerful software tool for inspecting component part quality and ensuring manufacturing process integrity.  The new software revision provides enhancements for acquiring, analyzing, viewing and organizing data from The Modal Shop’s market-leading resonant acoustic method (NDT-RAM) systems.

Version 7.0, now compatible with Windows Vista, also improves the usability of NDT-RAM systems.  Establishing acceptance criteria is a key function in the testing process.  Up to 20 criteria can be set for each test template, doubling the 10 previously allowable criteria.  This makes the software adaptable for more challenging applications or those where more data is required for analysis, such as brake component NVH.

Version 7.0 also offers the capability to increase the measurement resolution.  The maximum allowable FFT block size has been expanded from 8k to 32k.  The resulting improvement in frequency resolution allows the user to see more precision in the measured peaks, resulting in a more accurate analysis of the resonant frequencies.  In many applications, this increased resolution helps detect smaller defects.

With NDT-RAM 7.0, quality engineers can now record additional important data about each part tested.  An alpha/numeric description field has been added to allow information such as weight, lot number, serial number and orientation to be specified.  These descriptions are then listed with the NDT frequency results in the testing report.  This valuable tool saves time and enables the engineer to capture a more complete set of data.

New improvements in version 7.0 complement the upgrades seen in versions 6.0 and 6.1.  AutoLearn automatically optimizes the pass/fail testing criteria for each system, saving quality engineers a significant amount of time.  The ability to recall part investigation data eliminates the need to retest part samples against new limits.  Test data that previously took hours to analyze and experimentally verify takes just minutes with the analysis, organizational and data viewing capabilities of the software.  Multiple data sets can be used to generate statistical reports on demand without having to retest parts.

NDT-RAM systems are ideal for manufacturers of powder metal, metal injection molded (MIM), castings, forgings or stampings.  The industrial components and ease of automation make NDT-RAM perfectly suited for 100% inspection in the manufacturing environment. NDT-RAM systems, with the addition of software version 7.0, help companies that have substantial inspection costs, produce or use safety-critical parts, have significant scrap costs due to false rejects, or are striving to improve their part quality.  With no part preparation required, this technique can successfully identify internal and external flaws due to cracks, voids, material density inconsistencies, dimensions, porosity and nodularity as well as missed manufacturing processes.
