How The Sentinel Protects CNC Bits
<5MS LATENCY
1
Process & Window Auto-Hooking
Continuously monitors Windows message queue for active NcStudio.exe and PCIMC-3D control windows.
2
Acoustic Telemetry Link
Connects to Forge AI sensor stream over WebSocket, monitoring tooth-pass harmonics (600 Hz) and chatter anomalies (2.4 kHz).
3
Instantaneous Message Injection
Dispatches rapid WM_KEYDOWN VK_NEXT (PageDown) messages directly to the NcStudio window, throttling feed rate from 100% to 25% in < 5ms.
