Circular Milling

Aluminium or Aluminum is a relatively soft metal. It is light, but also durable, making it an excellent material to create useful parts for things used in everyday life. It had been a while since I tried to test different kinds of milling using Autodesk Fusion 360.

Fusion 360 has a really good way to create GCODEs for circular objects. It is similar to contour milling or profiling, but specifically meant to create circular or cylindrical objects with minimal wastage of materials.

I decided to make a couple of aluminum rings. Since a metal was being used to mill another metal, it was very important that the distance between each subsequent each step over was very small. Unfortunately, this meant that the process would create aluminum powder instead of swarf, and I had to be very careful while cleaning the OtherMill once the machining was completed.

Regardless, the finishing was beautiful and it actually did not need any extra polishing.
