Technical Reference
EDM Micro Cracks Guide
Microcrack acceptance must be tied to material, surface function, discharge history, inspection resolution, and sampling location. A vague “no micro cracks” note without method or magnification cannot be released or verified consistently.

EDM Recast Layer Guide
Recast always forms during EDM, but its service risk depends on the face. Fatigue, sealing, wear, corrosion, contact, and coating surfaces need a separate decision from Ra; noncritical edges may not.
Technical Reference
EDM Recast Layer Guide
“Remove recast” is not a complete requirement. A release-ready note needs the face, allowable layer or removal rule, method, sampling plan, and post-removal dimension.

EDM White Layer Guide
The white layer is the visible or metallographically observed resolidified EDM surface; its thickness and continuity vary with energy, material, flushing, and finishing. Assuming every white layer is harmless—or that every part…
