Are you engraving 1" square x 0.020" thick aluminum nameplates, or boring cylinders in cast iron engine blocks? 2) Degrees of freedom. If the magazine is lined up with the fixture, you could probably use only Z (pick up, put down), X (move between magazine and fixture) and A or B (flip part). Some sort of simple Cartesian slides could work. On the other hand, if you use a puma type robot with waist, shoulder and elbow, you might need 2-3 additional degrees at the wrist to keep the part in the proper orientation. 3) Size of the work envelope. Can the magazine be two inches from the fixture? Or is it several feet away? 4) Precision/accuracy. That is the only one of the four that you actually specified. Small workspaces with light workpieces and fewer degrees of freedom can be 1/10 or even 1/100 the price of large workspaces with heavy workpieces and many degrees of freedom. -- John Kasunich jmkasun...@fastmail.fm ------------------------------------------------------------------------------ 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
