So far I have been cutting almost entirely aluminum. As you all know you can make some big programming errors with no real problems in aluminum. I have done some cutting in steel and it has never really gone smoothly. Biggest problem is with chipping of the end mills. Really short life.

So here is the question. Can you guys post what parameters you are using to cut steel. I want to start at a point I know works on other Torus pros. I would like to know your 1) Depth of cut 2) Width of cut 3) RPM 4) end mill stick out from holder 5) End mill details ( Number of flutes, diameter, carbide or HSS) Coolant or not.

Are you using any of the online cut calculators to figure out where to start? If so are you derating the numbers or using what it says? If you found a feed and speed calculator that gives good data from the start which one are you using?

My first cutting will be with cold rolled steel.

Thanks for any replies.
