Slotting milling cutter, comprising a carbide body () and a ceramic head () fixed by brazing to one end of the body, this head having teeth (), each comprising a cutting edge () formed by the intersection between a front cutting face (A) and a lower flank face, in which the milling cutter has a frustoconical general shape, the profile of the flank face, formed by the intersection of the flank face with a plane passing through the axis of the milling cutter, has an outwardly convex rounded shape, and the radial cutting angle is negative.

Slotting milling cutter for machining with a high feed and a low pass depth

A surfacing and contouring cutter for high-speed machining of parts made of composite material, the cutter having a cut end portion with teeth () that are regularly spaced apart around the axis () of the cutter and that are separated from one another by swarf grooves, the main cutting edge of each tooth being connected to the secondary cutting edge (S) of the tooth via a corner () of convex rounded shape with a radius of curvature greater than about 1.5 mm, and the secondary cutting angle lying in the range about 5&#xb0; to 15&#xb0;.

Surfacing and contouring cutter for high-speed machining of composite material parts

A method for detecting and optionally a method for quantifying drilling anomalies in a metal part. The drilling method includes determining a value set of at least one of the two following parameters, depending on the time: the penetration axial stress of a drill bit into the metal part and the torque generated during at least one portion part of the drilling.
