Engraving Aluminum

I wanted to see if it was a good idea to engrave soft metals. Turns out, it’s a great idea. Not only is it easy, but also incredibly fast.

Even better is creating gcodes. In fusion 360, even though there is an option for engraving, it is not possible to use this with an engraving tool, because engraving is still considered milling by the software.

An easy way to get around that is by using the Trace option. And since I was using a simple sketches, it was extremely convenient to select the tool-paths. It is actually easy to engrave 2D sketches by using the trace option, rather than the engrave option. Engrave option is good only if you need a bit of a depth.

My choice of material was aluminum, and yes, they are dog tags.

I had to trace twice on the othermill because of the uneven arrangement of the material, yet it still took only about 25 seconds for each trace, i.e. both the sides were engraved in less than 2 minutes!

No, I did not speed up the video.
