What I'd do is have the holes rough cut on a CNC plasma table (they can cut aluminum, with the right setup) then do full depth profile cuts with the wood router gantry. A lot of those cuts, just past the point of chip thinning. http://www.mmsonline.com/articles/the-high-feed-high-reliability-process
If what goes into the holes has sharp corners you can drill them so when the end mill makes the turns it's cutting air or you can setup the path for it to cut past the corner both directions to leave open areas for the workpiece corners to fit into. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
