Milling cutter for face- and profile milling for high-speed machining of parts made from a composite material

摘要

The cutter (10) has a body (12) comprising a cut end portion with teeth (20) spaced around a cutter's rotation axis (14), where each tooth comprises a front main cutting edge and a side secondary cutting edge (S2). The main edge is connected to the edge (S2) via a corner (24). The corner is in convex round shape with a radius of curvature greater than 1.5 mm. A secondary cutting angle between a secondary cutting face of each tooth and a reference plane is negative and ranges between 5 and 15 degrees. The angle is measured in a plane perpendicular to the axis and a point of the edge (S2). An independent claim is also included for a method for high-speed machining of a part made of composite material.
