The machined surface (212) comprises a build surface (214) comprising a second outer boundary (220) of a pre-determined shape, and a transition surface (216) surrounding the build surface (214). The method (200) further comprises the steps of placing (108) the interim component (210) in an additive manufacturing device; determining (110) a position and an orientation of the second outer boundary (220); and additively manufacturing (112) a replacement portion (240) on the build surface (214).

The present invention relates to a milling tool for metal cutting comprising a body with a cutting head (1). The cutting head comprises a plurality of radially protruding and axially extending teeth, wherein each tooth of the plurality teeth comprises a rake surface, a clearance surface, and a cutting edge. The cutting edge, at an intersection of the rake surface with the clearance surface, extends axially rearward from a radially outer region at the front end. The cutting edge is continuous, and wave-shaped, and comprises alternating radially outer crest cutting edges and radially inner trough cutting edges. The clearance surface comprises a primary clearance surface, and a plurality of stabilizing clearance surfaces. Each of the plurality of stabilizing clearances surfaces is located rotationally directly behind a respective one of the crest cutting edge and has a radial stabilizing clearance angle β of 0,5° - 2°. The primary clearance surface is located rotationally directly behind each of the trough cutting edges and has a radial primary clearance angle α which is larger than the radial stabilizing clearance angle β.

The invention relates to a cutting tool comprising a substrate of a cemented carbide comprising WC grains, eta phase grains and Cr and at least one metallic binder selected from Co, Ni, and Fe, said metallic binder being present in an amount ranging from 6 to 22 wt%; wherein the weight ratio of Cr to said at least one metallic binder ranges from 0.13 to 0.30, and wherein the eta phase content ranges from 1 to 10 vol%.

A face milling cutter comprising: - a tool body (2) with insert seats (10), each of which having an internal wall with three support surfaces (21-23) that are distributed about a reference axis (RA) and inclined in order to form a cone-like guiding for a cutting insert; - cutting inserts (30) detachably mountable in different working positions in the insert seats, each cutting insert having first and second major faces (31, 32) on opposite sides of the cutting insert and a peripheral surface with several abutment surfaces (37); and - fastening elements (7) in the form of screws for securing the cutting inserts in the insert seats. The cutting inserts (30) and the insert seats (10) are so adapted to each other that the second major face (32) of each cutting insert is located at a distance from a bottom surface (11) of the associated insert seat when the cutting insert is mounted to the insert seat in any of its working positions.

The disclosure relates to a tool part (20a,20b,20c,20d) for a cutting tool (18) comprising an identification marker (40a,40b,40c,40d) arranged at the tool part (20a,20b,20c,20d) wherein the identification marker (40a,40b,40c,40d) is a unique machine readable code associated with individual dimension information data (idID), wherein the individual dimension information data (idID) comprises at least one individually measured dimension of the tool part (20a,20b,20c,20d) as measured when manufacturing the tool part (20a,20b,20c,20d) that will change while wearing the tool part (20a,20b,20c,20d). The disclosure further relates to a system (100), a method and a computer program product (500) for utilizing an identification marker (40a,40b,40c,40d) on a tool part (20a,20b,20c,20d) for a cutting tool, for determining a tool wear of the tool part (20a,20b,20c,20d).
