The EDM Recast Layer Problem: Why Surface Integrity Decides Aerospace and Medical Part Acceptance

Iron Machine Tool: Advanced EDM and Precision Milling Solutions | Minneapolis, MN A part can measure perfectly and still fail. In aerospace and medical work, the dimension on the print is only half the acceptance criteria; the other half is what the machining process did to the metal just beneath the surface....
