eZ-NDT Non-Destructive Test Software
Features
• Provides inspection of metal, ceramic, and hard plastic parts
• Removes the ambiguity that is common in other inspection systems
• Requires no parts preparation, making the test fast and inexpensive
• Tests parts in less than 2 seconds
• Quantifies and documents the first natural frequency for end user
comparison to final assembly resonant frequencies
You can use eZ-NDT (non-destructive test) software with a ZonicBook/618E to obtain a fast and
inexpensive method of 100% inspection of production parts. Inspection parts include, but are not limited
to: powder metal, ceramics, and composites. eZ-NDT uses acoustic analysis to identify part variations that
are caused by process inconsistencies and defects. eZ-NDT systems apply acoustic energy to the target
part, monitor its acoustic response, and analyze its resonant frequencies. It then compares the results to the
acoustic signature of a known-good part stored in its library. The test takes less than two seconds and
requires no special tooling, dyes, chemicals, cleaning, magnetization, or expensive and time consuming
visual inspection equipment.
eZ-NDT can detect deviations in dimensions, material properties, and defects including cracks, residual
stress, inclusions, and variations in hardness, tempering, porosity, mass, holes, bonding and/or welding
failures. Resonant inspection performs a whole body measurement, not just a spot check for visual
indications. It also quantifies the first natural frequency, which many end users require for comparison to
final assembly resonant frequencies. By keeping component first natural frequencies different from final
assembly resonant frequencies, the end user avoids the potential for noise, vibration, or product damage.
And because it’s fast, you can test all of your parts, not just a cross sampling.
Before purchasing an eZ-NDT system, we recommend that you engage in our Feasibility Study. This
study, discussed briefly in upcoming text, verifies that the intended inspection pieces will respond
appropriately to the eZ-NDT inspection process.
