Milling mild steel

[CharlesJenkinson]

I landed on the calculation of specific cutting force (SCF) whilst researching the other day. I get the feeling that fiddling around with some of the parameters in the SCF equation via the use of fancier cutting tools like the blue nanograin, and speeds/feeds and DOC appropriate to routers, that the actual cutting force comes down, for cutting materials like steel. And this is what makes cutting harder materials possible on a router versus the traditional milling machine, i.e. It's a different process.
