CNC machining
44 records: 7 read sources that cad-agent's rules and checks may cite, and 37 records catalogued from the Reference Map, not yet read. Milled and turned parts.
Catalogued records are search snippets: their numbers are the authors' claims and their licences are as the map states them, unread. Cite one only after reading the source and promoting it (how).
Coverage
What cad-agent checked for these topics when the map was made, and the gap it found. The issue it drafted for each gap was never posted.
PartlyCNC: internal corner radius, pocket depth, tool access
Gap: Rules in YAML only; dfm.check has no corner, pocket or tool-reach kinds and no geometry measurement; no 3-axis access/undercut analysis, thin-wall or tapped-hole depth checks.
Drafted issue, never posted: “Add CNC kinds to dfm.check and a tool-access analysis”
