The defense manufacturing process starts with controlled review of drawings, specifications, materials, and compliance requirements, including ITAR considerations when technical data is restricted. From there, the job is planned, programmed, machined, inspected, documented, and released under a controlled quality system. For precision parts, this often includes FAI/FAIR documentation, material traceability, in-process checks, and final dimensional inspection before shipment.
