Hi, I need to engrave each of my 56 aluminum (6061-T6) parts (otherwise, I'll never be able to tell them apart). So: (1) Any advice on router bit to use? (2) Any advice on feeds/speeds? (3) Any advice on DOC? Thanks Duncan
I just did this with 6061 about one month ago. It was my first attempt and I was kind of a chicken and was conservative. It worked well with a cheap 1.5mm PCB engraving endmill that comes in one of those cheap Amazon PCB engraving sets. I used 0.2mm depth of cut 400mm/min feed rate with a 6 degree ramp in and a 100 mm/min plunge rate at approximately 18000 rpms.
