The closure element (60) is settable in a closing position in the coolant supply recess in order to block the inlets (32a) of the second coolant channels while leaving the inlets (31a) of the first coolant channels unblocked.

The invention relates to a system (100) for controlling a cutting tool (110) during a cutting operation comprising a sequence of n operation steps, and wherein each operation step results in an operation condition, wherein the system (100) comprises a control unit (120) operatively connected to the cutting tool (110), and at least one sensor (112) operatively connected to the control unit (120), wherein the control unit (120) is configured to compare a measured value of the operation condition for a current operation step with an expected value of the operation condition for the current operation step and determining a difference between them, and, based on this difference, determine an adjusted expected value of the operation condition for the operation steps subsequent to the current operation step. The control unit (120) is further configured to determine if the adjusted expected value of the operation step is higher than a predetermined operation condition threshold value, and, in such case, reducing a parameter value of the cutting data parameter for the operation step.The invention also relates to a method (200) for controlling a cutting operation.

The invention relates to a method (100) for repairing a cutting tool component (200) comprising a damaged portion (202). The method (100) comprising the step of removing (102) the damaged portion (202) by machining the cutting tool component (200) into an interim component (210) comprising a machined surface (212). 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).

A double-sided cutting insert for use in milling with quadratic basic shape and eight different working positions. The cutting insert (1) comprises a peripheral surface (10), which extends around the cutting insert between first and second major faces (2, 3) and has four main side faces (11a-11d). One main cutting edge and one surface-wiping cutting edge are formed at an intersection between each main side face and the first major face (2) and at an intersection between each main side face and the second major face (3). Each main side face comprises a planar side abutment surface (13, 14), which extends between two corner side faces (12) of the cutting insert, and two inclined clearance surfaces (40, 50, 60, 70) located along and on opposite sides of the side abutment surface (13, 14), each clearance surface being convexly curved as seen in any plane that is perpendicular to a centre axis (C) of the cutting insert and extends across any part of the clearance surface.

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).
