Pick the thread, the material and how fast your inserts like to run. It gives the blank or bore size, the depths, the pass plan and the Fanuc G76 code ready to copy.

Fanuc G76 (two‑line, metric)
Check before running. This is written for a standard Fanuc control: two‑line G76, metric, X on diameter. Other controls, older one‑line G76 formats and machine parameter settings can differ.
Z0 is the front face of the part. Make sure your work offset matches, or adjust the Z values to your own datum. The start Z, thread length and end Z will be different on every setup.
Check the X values, tool offset, start point clearance and the rpm limit against your machine, tooling and drawing.
Prove it out with single block, a dry run or reduced rapids, and gauge the first part.
Pass plan (0 passes)
Fanuc G76 cuts a constant chip area: depth after pass n = Δd × √n, never less than the min cut, then the finish pass and spring passes.
Setup notes
Speeds, cut depths and pass counts are general starting values for coated carbide threading inserts, not any manufacturer's catalogue data. Thread sizes and depths follow ISO 261/724, ASME B1.1, BS 84, ISO 228, ISO 7 and ASME B1.20.1. Always prove the first part with a gauge or mating part.
