The exact routing varies by geometry and material, but a controlled sequence helps expose missing information before it becomes a machining or inspection problem.
Review and rough planning
Check revision, scale, units, material, hardness, datums, fits, corner conditions, surface notes, and inspection requirements. Select stock and establish roughing allowances around the thermal sequence.
Semi-finish and special processes
Plan datum recovery, heat treatment, grinding, wire EDM, sinker EDM, deep features, and any operations that may influence distortion or finishing access.
Finish and verify
Complete finishing operations against the approved datum plan, then inspect critical features using suitable equipment and record the agreed evidence.
