Deburr your parts like real machinists used to do- that part ain’t done until a baby can play with it

Deburr your parts like real machinists...

Negative. Use a small diameter solid carbide 45° or ball nose endmill to edge break EVERYTHING on the CNC machine. Thats the last step that any kickass programmer does and you do not fk around with parts that are $200K-$500K 3D printed nickle alloy where +/-.0002" and a 8-finish or better machined features are everyday occurrences. Now...if you're making door hinges in a mom and dad shop, sure whatever. Experienced machinists without fail will opt for programmed edge breaks. Every time. Hand debur is way to risky and explaining to management why a part is a NC (non-conformance) due to a blown finish from a hand debur makes for a very bad week for everyone.
