How to Use the Technical Reference Library

Use this library before sending a drawing when you need to compare EDM processes, understand tolerance or surface-finish limits, prepare RFQ details or clarify surface-integrity expectations.

Compare process options

Use comparison topics when you are choosing between wire EDM, sinker EDM, small hole EDM drilling and micro EDM.

Prepare drawing details

Use drawing, tolerance and material topics to check what information should be included in the RFQ package.

Review critical surfaces

Use surface finish and recast layer topics when edge condition, metallurgical effects or post-processing may matter.

Technical Planning Topics

Technical planning topics for EDM review

Use these reference topics to understand process selection, tolerance, finish, surface integrity and drawing preparation.

Wire EDM vs. Sinker EDM

Wire EDM is usually better for through profiles and narrow slots while sinker EDM is better for blind cavities ribs and shaped mold features.

  • Feature access
  • Through cut or blind cavity
  • Electrode strategy
  • Tolerance and finish

EDM Drawing and RFQ Checklist

A useful EDM RFQ should include drawing files material grade thickness or feature depth tolerance surface finish quantity and inspection requirements.

  • Drawing file type
  • Material grade
  • Critical dimensions
  • Tolerance zone
Read Technical Reference

EDM Tolerance Planning

EDM tolerance depends on material thickness feature geometry flushing pass strategy machine setup and inspection method so final values should be confirmed from the drawing.

  • Tolerance zone
  • Material thickness
  • Feature stability
  • Skim cuts
Read Technical Reference

EDM Surface Finish Planning

EDM surface finish depends on process settings finishing passes material behavior and post-processing requirements. Critical surfaces should be marked clearly on the drawing.

  • Surface finish target
  • Functional surface
  • Skim cut need
  • Post-processing
Read Technical Reference

EDM Recast Layer and Surface Integrity

Recast layer matters when the EDM surface affects fatigue contact sealing coating or safety-critical performance. These requirements should be stated before quotation.

  • Critical surface
  • Fatigue or contact function
  • Skim cuts
  • Post-processing
Read Technical Reference

EDM Inspection and Quality Control

Inspection planning should identify critical dimensions datums surface finish edge condition report needs and any functional surfaces affected by EDM.

  • Critical dimensions
  • Datums
  • Surface finish
  • Edge condition
