Separate functional and appearance surfaces
Identify the dimensions and features that control fit or sealing separately from the surfaces that are visible after finishing. This distinction helps keep machining, finishing, and inspection requirements clear.
List every turning, drilling, and milling feature
Document stepped diameters, threads, cross holes, flats, slots, and any profile details. The full feature set determines whether a turning-only process or a combined turning and milling discussion is more appropriate.
Confirm material and finishing sequence
Share the material grade, supplied stock condition, planned finishing process, and dimensions that need protection through subsequent operations. This gives the production discussion a usable sequence rather than isolated requirements.
