Metal: Cutting thicker than 0.25"

[WillAdams (William Adams (Carbide 3D))]

Folks have done very large/thick projects:

Nomad - Large Aluminum Part

I had a friend ask me to mill him a replacement handle for his old rowboat and I said yes before running the machining time simulation. As a result, I can say that the Nomad is capable of machining large aluminum stock, but it’s going to take a while. [image] I started with a 8"x6.5"x1.25" thick piece of 6061-T6 aluminum and used an 1/8" 2-flute ZrN coated end mill from lakeshore carbide for the majority of the roughing. I also had to order a long reach end mill to get through the full depth …

the 0.25" caveat is more a matter of machine run time and managing expectations.
