An introduction to cryo‐FIB‐SEM cross‐sectioning of frozen ...

FIB‐milling of a frozen hydrated sample under 'cryo' conditions is similar to FIB‐milling of any other solid, although the sputter yield is unusually high (Marko et al., 2005, Fu et al., 2008). Scan strategies for efficient milling vary by manufacturer, but standard FIB‐milling procedures can be followed for making cross‐sections ...

Solved: Bad 2D Contour Tool Path at Fillets - Autodesk ...

I'm trying to mill a shape with a fairly complex outer perimeter. I cannot select the entire outer permitter as one contour, and if I select the segments in order I get this weird tool path behavior, see the screen shots. It clearly doesn't see it as a continuous edge. I've tried: Making a smaller model, that only has a few of these features.

Optimization of mill performance by using

charge motion. It is well known that ball milling efficiency varies during the lifetime of the shell liner. For instance, the mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty.
