Forces in X,Y and Z

[routercnc]

In the past I've used the numbers in post #6 (which came from Irving) for deflection calculations in the absence of anything else. At least you can then start comparing designs with each other.

Recently I found these from Kistler (manufacturer of measurement sensors). For milling they show typical forces (I assume cutting steel with ~8mm tool going by the picture?) of about 160 N?

Also attached turning and drilling for info.
