This is my first instructable and these are my cog tags from the video game Gears of War.
My cog tags are made out of 3mm aluminum and were both engraved and cut out using a CNC Mill
Step 1: Engraving And Cutting Out
First i engraved the aluminum and then cut it out on the CNC mill.
I used a 60 degrees vbit for the engraving and a 3mm ball nose bit for the cut.
Found that cutting it out at a slower speed gave the best results.
