Noise, vibration and harshness (NVH) testing on the factory floor poses its share of challenges....

Proof that your station is ready to build quality product

Routine and automatic machine-to-machine comparisons using signature data can help identify tooling and machinery problems before they result in a high number of defective products being produced.

The signature below is from a pull and release operation on a polymer. The green curve shows evidence of a part slipping from the tooling (in top red circle), though it wasn’t visible to the naked eye. We can also see that the servo motor is generating more friction than it should (in lower red circle). These signs show that maintenance is required on the system and that additional degradation may affect quality and yield.

The data can also be used to expedite run-off on new stations, particularly if they are clones of existing machines.
