How does one ensure the feed speed does not exceed the milling speed of the cutter? Answered
When milling any material, if the speed of the axis drive exceeds the capability of the cutter/stock capability rate, the stock will deform or the cutter will overheat, or the axis will jam. Conversely, if the axis is driven too slow,well, that's too slow!
One more, all of the designs I've perused thus far are utilising phase counting to determine where the cutter is, in other words, there seems to be a lack of tracking feedback. So, how does one ensure a 4" circle is a 4" circle and not a 3.5"x3.75" ellipse?
