I got the chance to use one of the boards that I made and mentioned in a previous post.
I CNC’d a corner of this board to re-make my Change Tray project so that it can more accurately count out a roll of coins in the slots. In the original project, I discovered, the hard way, that the full diameter of the finishing ball end mill needed to be accounted for when defining the finishing constraint vectors.
Roughing Passes
Roughing passes are used to remove a lot of material quickly. A 1/4″ end mill was used to mill the center of the tray and the define the outer edge and the coin pockets.
After the coin pockets were finished, text was added to the bottom (coin values) and top (roll coin totals). The tray is then cut out and freed from the stock.
All that was left was some light sanding and oiling.
