Resumo :
ABSTRACT. WE HAVE MEASURED THE WEAR OF THE RAKE FACE, OF THE CLEARANCE FACE AND OF THE CUTTING EDGE OF CUTTING TOOLS, WHICH HAVE BEEN MANUFACTURED WITH TUNGSTEN-CARBIDE TIPS, WITH A HIGH SPEED STEELM4, WITH AN AISI-D6 STEEL AND WITH AN ABNT (AISI.01) STEEL , DURING THE MACHINING OF THE "EUCALIPTUS - GRANDIS" WOOD, WITH HIGH MOISTURE CONTENT. THE WOOD MACHINING TESTS WERE CARRIED OUT WITH A SPECIAL DIVISE, IN ORDER TO HOLD THE TOOLS, SIMILAR TO A FACE MILLING CUTTER, TO WHICH TWELVE CUTTING KNIVES WERE FIXED, BEING THREE TOOLS OF EACH MATERIAL ALEATORY DISPOSED.THE TEST WAS CARRIED OUT IN A MOLDING MACHINE, ON WHICH WE SET UP A BUILT TOOL HOLDER AND ATTACHED A FEEDER FOR THE WOOD TEST PIECE WITH STEPLESS REGULATION SPEED.WE HAVE MEASURED THE WEAR WITH A PROFIL PROJECTOR WITH A 50X ERLARGEMENT AND WE HAVE DRAWN ITS WEAR GRAPHS IN REGARD TO THE CUTTING LENGTH.WE INFERED THAT IT IS ENOUGH TO MEASURE THE WEAR OF THE CUTTING EDGES OF THE TOOLS AND / OR THE WEAR OF THE CLEARANCE FACE OF THE TOOLS.
