Show: CNC Milled Batman Tag

Here is something I did back in high school. We had to take a piece of aluminum and come up with a design to program a CNC mill to make.

I ended up making a Batman design. We had to draw a to-scale version of the design and mark coordinates of points on the design such as the beginning and centre of the arcs and the start and end points of straight lines. We then programmed all of these points using G code to tell the CNC mill how to cut it out.

Here is an example of G code. The code was for a CNC lathe for a different assignment I did but it is similar to what I had to do for the Batman tag.
