Subtraction – Week #8 4 Axis mill

This week we learned about the 4 Axis mill machine in the shop. The machine looks promising and there’s not a lot of people that actually know how to use it at itp..

We had in class demo how to use it, I took some pictures to remember the order of operation. In order to use this machine we start by making a 3d model- which we can download or use vectorWorks to make one. It needs to be an STL file. This machine can mill aluminum, wood, Delrin, brass – Also cubic stock or round stock.

My first tryout was an poop emoji that I downloaded from a 3d print model, planned to be cut from foam, just to test the machine.

From my first test I figured that I need to use material that close in size to the original model. The bit requirements sometimes not realistic to the bit I have so I need to readjust the size in order to fit the material and tools I have. So I tried to make another foam test. This time it was a duck.

This time, the machine just skipped the roughing path. so I had half duck.
