Threaded parts need complete drawing information
Threaded parts machining is not defined by the word "thread" alone. The drawing should identify the thread form or standard, nominal size, pitch, internal or external type, handedness and class or fit. Include the material and part quantity so the feature can be reviewed in its manufacturing context.
Dimension depth and surrounding geometry
State the required full thread depth and identify lead-in, relief, counterbore, clearance or runout features where they affect assembly. Show the relationship to the part datum and nearby features. A blind hole may need a defined usable thread depth separate from its drilled depth.
Connect the thread to its mating part
Include the mating-part callout or assembly context when it helps confirm the intended fit. If the application needs a particular sealing, locking or engagement condition, state the requirement. Do not assume thread fit from a generic model or an unverified tolerance note.
Plan inspection with the callout
Identify whether a thread gage, measurement record or mating-part check is required. The inspection method and acceptance requirement should be agreed for the drawing. For process-specific context, see our les services de filetage CNC page and options de filetage.
Préparer une demande d'usinage
Send the drawing and 3D model when available, plus material, quantity, thread callouts, critical dimensions, finish and inspection needs. The team can review the part and clarify any incomplete thread requirements before confirming the quotation.
