![]() ![]() So I would start with a scallop which will give even stepover. The ideal option for the rest would have been steep and shallow but that is paye foreven with the non free version, I usually set the adaptive to leave 0.3mm then the contour is done with one roughing pass at 0.2mm stepover leaving the final finish pass to remove 0.1mm I would use a 2D contour to finish the main outer diameter. I'll be using a 3mm ball end 2 flute cutter and the spindle can run up to 10,000 rpm.Īny suggestions including feeds, speeds and step-overs for initial attempts would be gratefully received. There are a lot of alternatives even in the free to use version! To this end I have drawn a simple test piece to be cut from 1" square aluminium alloy:Ī 3D adaptive clearance should rough it out OK but I am at a bit of a loss as to what to choose for finishing. I have decided that it's about time I investigated the 3D milling capabilities of my Denford/Sherline Mach3 converted mill. ![]()
