2012-4-25Effect of end mill run out A series of micro milling tests was performed for verication of the effect of the end mill run out. In order to supply the required data for the model, the maximum radial displacement and its angular location, with reference to the rst cutting edge at the tool tip, were measured on the tool shank, after clamping, at two different axial levels.

2018-12-13chromite rich fraction through the ball mill. This circuit is typical of a UG2 plant in which maximum silicate with minimal chromite breakage is targeted. As a result of the circuit change an opportunity for optimisation around the industrial scale ball mill was considered for this study.

For chromite, the mill solids did not appear to have any effect at low ball fillings, but a slight shift was observed at the higher ball fillings tested. The trend suggests that the size reduction of both silicates and chromite increased with an increase in ball filling, albeit at different rates.

End milling An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.
