All the same, I still say you have to make the trade-off for your machine: push it too hard (to get the short cycle time) and you may get chatter. Me, I would be more concerned about the chatter than the cycle time.
And a chattering machine is going to wear out a lot faster too.

I agree with you. But my problem with the regular endmills i have tried. I won't get anywhere near the material removal as with the indexable. I have tried low DOC and wide WOC, up to 10mm DOC with low WOC, but it seems to chatter no matter what I do. I always run HSM toolpaths. In fact it wants to chatter even for the finish pass. I can't leave more than 0.1 mm 7mm DOC finish or else I get chatter. Anyone having recomendations for steelcutting endmills that works good with the Torus?
