T N M GReference workflow
V1 confirms a verified code and geometry reference where a source record exists. It does not choose a grade or predict cutting performance.
Popular reference
CNMG 432 is the ANSI designation mapped in V1 to ISO CNMG120408. Different markets can use different designation formats for a base size combination. V1 only returns mappings supported by the local verified data.

Technical confidence
We normalize supported code formats, retain a source with each verified size record, and show a pending status when technical evidence is incomplete.

Open sourceYes. V1 recognizes CNMG 432 and CNMG432 as the same supported code.
Yes. The verified V1 record maps CNMG120408 to ANSI CNMG 432.
No. Grade, chipbreaker, coating, workpiece material, machine condition, and cutting parameters still require separate validation.
