So i dont speed then and cut at finishing speeds. As at the end of 3-4 days work if i have chipped say every five from 100 pieces it would be like 50 pieces to repair. Which is tremendous amount of time lost and material, if its unrepairable.
Yes exactly, which was my point. That's the material dictating the feeds not you deciding to go slow. I'm sure if you could with same finish etc go faster, then you would.

End of the day it's mostly the material and tools that dictate the feeds n speeds required and not something the machine should dictate because it's under specified or poorly designed. Like wise the user's choice in feeds n speeds is limited to a small range if they want to cut correctly and not destroy tools or materials.
