You also don't have to worry about me going to jail for defacing US currency since it is for artistic purposes.
By the way Dennis, your cube is ready ;-)

My little sister, Amy, is a bit of a
Disney nut. When I told her my mill was running she asked if I could
stamp pennies. She wanted to know if the mill could do something little
like the classic Mickey Mouse silhouette. Always up for a challenge I
clamped a penny in the vise and did some CAD/CAM work. Click on the picture to see more detail. |

I first found the ratio from the ears to the face to be about 0.5952 but then decided the basic silhouette wasn't enough of a challenge. After pressing the start button, 8 seconds later, this appeared on the penny. |

Here is a close-up showing a bit more
detail. Don't even ask about how to buy one, I'd rather not face a room
full of Disney lawyers on a copyright infringement lawsuit ;-) You also don't have to worry about me going to jail for defacing US currency since it is for artistic purposes. |

Making chips on a replacement Christmas gift for my brother Dirk. I had planned on casting a coaster for him but I ran into problems with the CAD/CAM software and ran out of time. I sent him a preliminary pattern with a promise to replace it later. |

A quick blast of compressed air and the result is clear. This was a chance to test out the new v-carving ability in the software. It is a 3D carving routing that determines the depth of the engraving based on the width of the letters. It works fairly well. The choice of font was to be cast so it doesn't really show off the capability of the software. |
|
|
I gave the coaster a coat of paint and when it was cured I sanded it off the face leaving the paint in the letters for contrast. I hope he likes it. |

Here the mill is pocketing out a turners cube. An apprentice lathe operator would be handed one and told to figure out how to make one. I always thought it would be a cool CNC project and used it as an opportunity to learn the 3D modeling side of my software. To the left of the cube you can see the nozzle for a Kool Mist system which sprays a fine mist of a water based coolant/corrosion inhibitor along with compressed air to remove the chips and improve the surface finish. |

|
Here is the end result. I should have
included something for size reference, the cube is 1 1/4" on a side. It
begs to be picked up and spun between your thumb and finger. I think
I'll have to make a stand for one. By the way Dennis, your cube is ready ;-) |

It turns out they are like potato chips, you can't make just one! |
