EDM Inspection Report Guide Technical Reference
An EDM inspection report should list the released drawing revision, measured features, datums, method, result, units, and any surface or metallurgical checks. An inspection report is unusable when it does not identify drawing revision, datum, feature, method, units, acceptance limit, and sample quantity.
Quick Answer
An EDM inspection report should list the released drawing revision, measured features, datums, method, result, units, and any surface or metallurgical checks.
RFQ Preparation Points
What to Send
Adding CMM, roughness, recast, or metallography after production may require a new setup or new samples. The consequence changes fit, function, or service performance for the Inspection Report decision; it is not only a change in surface appearance.
How to Use the Files
Define report scope before machining so the fixture, datum, sampling, and destructive-test allowance can be planned. When planning Inspection Report, apply the requirement only to the dimensions and faces that control fit, function, service life, or documented release.
What Causes Delays
An inspection report is unusable when it does not identify drawing revision, datum, feature, method, units, acceptance limit, and sample quantity. Data without traceability cannot release the part.
What Each Input Does
A controlled EDM review separates geometry files from requirement files. The model defines shape; the drawing defines material, tolerances, functional surfaces, datums, revision, and inspection. Missing either one forces assumptions that must be resolved before production. This mechanism explains the limits and behavior that matter when planning Inspection Report.

| What you're asking | What you can expect |
|---|---|
| Input | Purpose |
| 3D model | geometry and programming |
| 2D drawing | material, datums, tolerance, surfaces, notes |
| Quantity | prototype and batch planning |
| Inspection | method, report, and acceptance |
| Revision | controls the released requirement |
How the Review Uses the Information
Use a preliminary marked sketch for budget guidance, then release a controlled model and drawing before production. An inspection report is unusable when it does not identify drawing revision, datum, feature, method, units, acceptance limit, and sample quantity.
Inspection and Surface Inputs
The drawing should identify which dimensions, surfaces, edges, and reports are required. Missing surface or inspection information should be listed as a quotation assumption, not silently converted into a default requirement. For Inspection Report, tie the accepted condition to the feature and inspection method named in the drawing.
Inspection Report Drawing and Release Checkpoints
- Identify the controlled feature, material condition, access direction, and functional datum for this Inspection Report decision.
- Separate dimensional requirements from texture, edge, recast, corrosion, fatigue, or post-process acceptance.
- State the inspection method, sampling or first-article requirement, drawing revision, quantity, and any documentation needed for release.
Practical Next Step
The drawing should identify which dimensions, surfaces, edges, and reports are required. Define report scope before machining so the fixture, datum, sampling, and destructive-test allowance can be planned.
What to Remember
An EDM inspection report should list the released drawing revision, measured features, datums, method, result, units, and any surface or metallurgical checks. A release-ready RFQ removes assumptions about geometry, material state, quantity, finish, revision, and acceptance evidence.

Frequently Asked Questions
Is a 3D model enough?
No. It does not release material, tolerances, surfaces, or inspection.
Can a sketch be quoted?
Yes for a rough budget; production needs controlled files.
When should inspection be defined?
Before quotation and setup.
What causes the most delays?
Missing material condition, datums, functional callouts, quantity, or report scope.
