Abstract: A face milling cutter includes a tool body provided with several primary cutting inserts including a pattern forming insert with a pattern forming cutting edge for forming a grooved pattern in a milled flat surface formed on a workpiece by the primary cutting inserts, and a calibrating insert with a calibrating cutting edge for cutting summits in the grooved pattern. The pattern forming cutting edge is wave-shaped as seen from a direction facing a rake face of the pattern forming insert with a periodic wave shape having a plurality of wave crests and intermediate wave troughs. The calibrating cutting edge is located axially between the wave crests and wave troughs of the pattern forming cutting edge, as seen in a direction from the rear end of the tool body towards the front end of the tool body in parallel with the longitudinal axis of the tool body.

Abstract: The present disclosure relates to an additive manufacturing (AM) process for making a three-dimensional (3D) object, using a powdered polymer material (M) comprising at least one semi-crystalline polymer or copolymer (P), in particular to a 3D object obtainable by laser sintering from this powdered polymer material (M).

Abstract: A milling device is rotatable in one direction around a longitudinal center axis defining a forward direction and an opposite rearward direction, and includes a front part and a rear part. The front part has cutting edges, each having a longitudinal extension, and chip flutes, each having a longitudinal extension. The front part is made of a monolithic piece of ceramic. The rear part is configured to be fixed in a rotatable tool body or a rotatable chuck. The rear part is also made of a monolithic piece of cemented carbide. A front end surface of the rear part has a smaller area than a rear end surface of the front part. The front end surface of the rear part and a rear end surface of the front part are permanently bonded or brazed to each other by a joint.

Abstract: The present invention discloses coated inserts particularly useful for milling of compacted graphite iron under wet conditions at moderate cutting speeds comprising a cemented carbide body and a coating. The cemented carbide body comprises WC, from about 7.3 to about 7.9 wt-% Co and from about 1.0 to about 1.8 wt-% cubic carbides of Ta and Nb and a highly W-alloyed binder phase. The radius of the uncoated cutting edge is from about 25 to about 45 ?m. The coating comprises: a first, less than about 1 ?m, TiCxNyOz layer adjacent to the cemented carbide having a composition of x+y=1, x is greater than or equal to 0; a second, from about 1 to about 2 ?m, TiCxNyOz layer having a composition of x greater than about 0.4, y greater than about 0.4 and z is less than about 0.1 and equal to or greater than zero; a third, less than about 1 ?m, TiCxNyOz layer having a composition of x+y+z greater than or equal to about 1 and z greater than about 0; an ?-Al2O3-layer with a thickness of from about 2.1 to about 3.
