Ava investigation
SIMULATED EXAMPLE · NOT A LIVE DIAGNOSIS
Unusual spindle noise. Job stopped.
Simulated operator report: “I heard a new noise from the spindle area during a job. The job is now stopped. What should we check next?”
Fictional symptom only. No real alarm, inspection or repair result is claimed.
Confirm the exact machine first
In this simulated case, the operator selects a Haas VF-2 with an NGC controller. Ava separates that reported configuration from details still needing confirmation.
- Confirm the model and serial number against the machine record.
- Record the controller generation and installed software version.
- Keep the incident linked to this machine, not another VF-2 in the shop.
Known for this example: an operator reports unusual spindle noise and a stopped job. The cause is unknown.
Remember the outcome, not just the guess.
Ava can reference dated conversations, previous incidents, maintenance and recorded repair outcomes on the same authorized machine.
Operator reports
Symptoms and earlier questions remain reported observations.
Human-confirmed outcomes
A manager records the diagnosis, work, parts, technician, date and outcome before confirmation.

Verified vs. possible
AVA labels documented information separately from probable causes and cites the source document and version when available.
Safety first
For dangerous electrical, mechanical or machine-control procedures, AVA requires appropriate qualifications and lockout/tagout precautions — and will refer you to a qualified technician.
What AVA is built to understand.
Program review preserves originals and tracks reviewed copies. Controller-certified validation, toolpath simulation and collision checking are not connected. Qualified machinist review is required before production.
