Experimentals asspects regarding multi-flute twist drills wear

Résumé

The problem of twist drills behavior in the cutting process, from the wearing point of view, is defining for the characterization of the quality of the tool. Another element which influences the quality of machined part is the machine-tool itself. In this paper was analyzed the process capability in case of boring with a HAAS machining center using multi-flute twist drills. The tests concerns about the holes position and diameter. The measurements were made using a coordinate measuring machine Tesa MicroHite 3D.
