摘要

Cutting tool for milling the front of composite material, corresponding method of milling cutting front, gum and the body of the tool.The present invention relates to a cutting tool for milling the front of a workpiece (20) ompreendendo receptacles of gum (62, 64, 66, 68) for the attachment of cutting inserts (32, 34, 36, 38); cutting inserts (32, 34, 36, 38) have the ability to be fixed In the receptacles of gum (62, 64, 66, 68).In accordance with the present invention, the cutting inserts (32, 34, 36, 38) and the elements of gum (62, 64, 66, 68) are designed in such a way that / when the cutting inserts (32, 34, 36, 38) are fixed in the corresponding receptacle gum (62, 64, 66, 68), CAD The cutting insert (32, 34, 36,38) features: a primary cutting edge (40) for radial machining of the workpiece (20), a secondary cutting edge (44) associated with the primary cutting edge (40).The secondary cutting edge (44) and an edge cleaning for the machining axis of the work piece (20); the intersection (42) between the primary cutting edge (40) and the secondary cutting edge (44) of the second wafer cutting (34; 36; 38) being axially and radially internally externament And displaced [offset] (offset) from the intersection (42) between the primary cutting edge (40) and OAThe secondary cutting (44) of the first wafer cutting (32; 34; 36); and a driving angle (KR) of each of the cutting inserts (32, 34, 36, 38) defined between the primary and secondary cutting edges (40, 44) being less than 300.
