I have been visiting this forum for quite some time now (it's brilliant) and have finally plucked up the nerve (...well had to) to ask a 'probably lame' question in the hope that someone can throw me a lifeline.
I have modeled this item (pic #1) in Rhino V4 and setup the MOP in Rhinocam V2. My problem is can't figure out how to get full (true) 4 axis machining on the piece. My cnc machines the item out using z, x and a axes only but not y. In other words the item is machined on a rotational, incremental basis turning on the x axis as in (pic #2) while the tool transverses along the centre-line (z axis). Unfortunately the result is I have 'dead zones' that can't be accesses by the tool.
I found an article where a guy (a lot smarter than I am ) is using Visualmill to make RC model aircraft undercarriages (pic #3) and uses the sort of toolpaths that I would like to achieve. Assuming that Rhinocam 2 is pretty much the same as the stand-alone Visualmill, I'm thinking that I seem to be missing something in my MOP setup, which can be seen in pic #2.
So...has anyone got the answer I seek?
