Ammonia synthesis by mechanocatalysis in a ball mill | …
Mechanocatalysis in a ball mill makes it possible to synthesise ammonia at much lower temperatures and pressures than those required for the Haber-Bosch process. This has been observed by a research team led by F. Schüth and S. Reichle from the Max-Planck-Institut für Kohlenforschung.
A new approach to analysing machined surfaces by ball …
This paper presents a procedure for the evaluation of maximum surface roughness using the ridges analysed in part 1 of this paper. Maximum surface roughness is predicted for the plane cutting mode of ball-end milling. Two types of cutting modes, i.e., unidirectional mode and bidirectional mode, are investigated. The various cutting conditions in plane cutting are simplified employing the ...

Using smaller radii on the .250 tool actually makes the cut marks worse, since it uses the edge of the tool more as the tool moves over the LE curvature. A five axis machine would reduce the work a bit :-). Ball mills make it a little better but the stepover needs to be even smaller yet.
