Nick needed to make some fake WWII gold for an escape room game. Brass was used as the material so that bars had some heft to them. Each bar weighs approximately 800g but feels satisfyingly heavy.

The toolpaths were produced using Fusion 360 and cut using the CNC Mill. The reference model was taken from thingiverse: https://www.thingiverse.com/thing:2442031

The first operation was done with a 6mm flat end mill. The 2D Adaptive option was used to give a smooth cut with 1mm optimal load and 1mm depth cuts.

The second operation was done using a 1.5mm ball nose tool. Parallel passes were used to produce the text with good results. The only problem with this approach is that the cross hatched tooling marks are plainly visible on the surface.
