Involute CNC'ing

[Dubric]

Can I machine a involute shape (impeller vanes) on a three axis machine such as a Mazak M5, ATC40, or 15SQT's or VMC 16 or 20's all with conversational heads (T32, Mazatrol, etc.)?

or

On what model Mazak machines can such a shape be machined?

Thanks in advance for any direction here.

You can with the right fixturing.

Can you elaborate?

You need some way to hold the impeller "upright" and then be able to rotate it and reliably locate it for machining of each vane. Most would add a 4th rotary axis to a 3 axis machine to do this. An indexing head could work.

On a side note, if you cannot envision this type of work holding, you are not knowledgeable enough to be tackling impellers.
