Hear the contact.
Acoustic emission — high-frequency elastic waves released at the tool–workpiece interface — is the most direct process signal in grinding. It is only useful at a sampling rate ordinary data acquisition does not reach, and only inside the contact window. Toleron handles both.

What the signal carries
Grain–workpiece contact, chip formation, friction and wheel wear all emit in the kilohertz-to-megahertz band — far above what ordinary data acquisition captures, and only meaningful while the wheel is actually cutting.
How Toleron acquires it
Industrial AE sensors on the lab's grinders feed a dedicated high-speed digitiser path on its own EdgeBox — acquisition validated end to end into the permanent archive. The raw stream is a signal like any other: streamable, recordable, and usable by AI at the edge.
Gated to the cut
The platform gates acoustic emission to the physical cut and computes features only inside it, so every window describes the process rather than air time or a setup change. Those features feed the wheel-condition model.
