After a few failures and a lot of stress about this project I finally have some momentum forward. I tried milling out the wax on my CNC Taig Mill but I ran into some snags. The mill was working great until I came to the finishing operation. This is when it would all of a sudden shift to the right and throw of the whole design. I talked to Frankie about what the problem was, he informed me that the Taig will sometimes miss steps in the operation if ran to long. Thankfully, he let me use his Tormach Mill, which is a lot beefier!
I have changed my mind about showing the piece as I stated at the beginning of this project, at least for this part! I want to document this because I am super proud about this step, both in design and milling intensity.
There were several things that made this a challenge more than the other CNC operations I have done. This is the smallest and most detailed piece I have done and it has a backside so I had to do a flip. The reason this is so scary, stressful, and nerve racking is because if you don’t have a good index system and you flip it and its off the piece is ruined!.
That is a lot of pressure in my opinion, but something I really wanted to be able to learn and do! Thankfully again, Frankie was there to help me out and show me one way of indexing it for the flip. He also brought up some good points on how to better write the code to speed up the time spent making it more doable on my machine.
It is amazing how much I have learned with just this aspect of my project. My confidence in using a mill, how to write the code, and being able to do advance operations. I am really happy with how it turned out, now I just have to successfully cast it!
