Comparative study of drill’s flank geometry developed with the catia software

Résumé

The paper presents a comparative study for the geometry of standard twist drill’s flank as oppossed to curved multi-edge drills for a similar sharpening process, on a cylindrical surface. Developed through the resources provided by graphic design CATIA software, the study refers to the shape of the face, the variation law of the tool normal clearance, along the cutting edge and to the clearance of the face.
