Define what 'micro' means on the drawing
Micro wire EDM is a term buyers use for small or intricate cut features, but it does not define a minimum feature size or tolerance by itself. Dimension the slot, profile, corner, start hole and related datums, and state which surfaces control fit or function.
Confirm the material and cut sequence
Provide the exact material grade and condition. Identify the feature access, part thickness, start-hole requirement and any rough/finish cut sequence required by the drawing. If the material or geometry is unusual, request a feasibility review rather than assuming the process can meet an unstated limit.
Plan how the feature is checked
Specify the inspection method, units, report and acceptance criteria. Note small edges, thin sections or dimensions that need special handling during measurement. Include the current drawing revision, quantity and any secondary finishing.

Micro-feature RFQ checklist
- Material grade and part thickness
- Dimensioned profile, slot and datums
- Start-hole and cut-sequence requirements
- Critical dimensions and inspection method
- Quantity, finish and report needs
Have the supplier review the drawing and measurement plan before treating a small-feature limit as confirmed.
