Drawing Review Comes First

Before machining begins, the drawing should clearly define material, dimensions, datums, threads, surface finish, quantity, and any important assembly interfaces.

Where information is unclear, technical questions should be confirmed before production rather than assumed during machining.

The Process Should Match the Geometry

Critical Features Need More Attention Than General Geometry

Bearing fits, locating holes, sealing surfaces, related bores, threads, mating faces, and assembly interfaces may require different machining and inspection priorities from non-critical areas.

The drawing should determine where tighter control is needed instead of applying the same requirement to every surface.

Secondary Operations Should Be Planned Early

Revision Control Matters for Repeat Orders

Custom parts often change during development. When dimensions, material, finish, or features are revised, the latest drawing should become the clear reference for future production.

Keeping revision information aligned helps reduce confusion when the same part is reordered later.
