Thanks for your responses,
I am a little wiser.
I guess I will have to start with the maximum power requirements of the cutters at the speed and feeds I will use and factor in machine induced loads.
I have a feeling that if I do not use a big enough stepper I will have to sacrifice
rapid traverse speeds for more cutting power by gearing down motor lead screw ratios.
I still have some study to do to get a handle on this.
Thanks again
