Magnaflux has developed Process Compensated Resonant Inspection as a high production nondestructive test for defects that can cause structural failure in subsequent machining, assembly, or service. PCRI is typically used on ferrous and nonferrous castings, forgings, powder metal, and ceramic parts. |
Quasar Process Compensated Resonant Inspection (PCRI) is a powerful, yet flexible NDT method that provides reliable results at substantially lower costs.
Quasar PCRI provides effective resonance inspection in the presence of typical manufacturing process variations. Using PCRI, defective parts can be reliably rejected on the production line because PCRI results correlate directly to part performance.
Quasar PCRI will
- Provide you with a means to predict part structural and performance integrity.
- Eliminate the potential for human error from the inspection process.
- Lower costs per inspected part in high volume applications.

The Quasar PCRI technology is built on 5 critical elements:
- Use of mechanical resonances provides the basis for correlation to structural performance
- The system compensates for normal changes in the manufacturing process such as die wear
- Temperature compensation which maintains frequency precision independent of part temperature
- Precise frequency measurements that establishes the acceptable part requirement
- Sturdy base provides shock isolation that prevents interference from shop floor vibration
How Quasar PCRI Works
The resonant frequency of a part is based on its stiffness and mass. The Quasar method measures several resonances for each part and uses a proprietary pattern recognition algorithm to compensate for the acceptable process variations.
Implementing the Quasar system requires a "Training Set" of parts (approximately 150 -200) that have been produced at different stages of the die's life, production process, and includes known rejected and accepted parts. This variety of parts will train the system to create an acceptance frequency range.
Once the system is trained it is ready for high volume inspection. The Quasar drive transducer sweeps the parts through a range of frequencies. The Quasar software measures each of the frequencies at which the part resonates and compares that pattern of resonances to the pattern of an acceptable part. The system then performs a statistical analysis on the pattern, decides if the part is acceptable and then notifies the operator with a green (accept) or red (reject) light.
