Certification

Why Certification Verification Matters Material certification verification is not paperwork. It is a quality check that prevents scrapped parts, broken tools, and failed components. I have seen the consequences of skipping this step. A material that does not match the print specification can fail under load, especially in aerospace and medical applications where the margin of safety is small. But even in less critical applications, wrong material causes machining problems. ...

I set up an operator certification program at a shop that was having quality consistency problems between shifts. The day shift produced good parts with scrap rates around 2 percent. The night shift regularly scrapped 8 to 12 percent of parts. The machines and programs were identical between shifts, so the problem was clearly in how the operators were running the jobs. The certification program was designed to bring every operator up to the same standard. Deep hole drilling demands specific skills that general machining certification does not cover, so I built the program from scratch. ...
