Just curious but what would you say is a resonable time to machine this part in?

Forgot to mention, just the inner profile, drilling the 4 holes, also tapping them.

Material? Tolerances?

[jrobson]

Suppose that would help Aluminum 6061, Tolerance is 0.025mm on the 5mm high walls, other than that not very important, BUT I do get a nice mirror finish on the walls so yeah you can push it but of course the finish must not suffer too much.

I am cutting it with 2 Flute Alu-Cut cutters @ 10000rpm(max of the machine) and am running 1:30 flat per part cycle time, would like to know how close I am to optimum with the 2 flute cutters, when I wear them out I'll move over to 3 flutes and should cut 20 seconds or so, but my supplier didn't have any.

Roughing with 8mm, finishing with 4mm.

Jonathan.

Sample attached...

1:30 sounds like you're pretty close to optimum. I took your .xt file and put some toolpath to it in MasterCam. I got a cycle time of 1:50 without really looking too deeply. With some tweeking it could get somewhat better but sounds like you're on target.

Cool thanks for taking the time, very good to know.
