Flintstone2020 aims to provide a perspective for the replacement of two important CRMs tungsten (W) and cobalt (Co) which are the main constituents for two important classes of hard materials (cemented carbides/WC-Co, and PCD/diamond-Co), by developing innovative alternative solutions for tooling operating under extreme conditions. Fundamental knowledge on mechanical properties and wear of different tools, gained in machining tests and dedicated experiments from WP1 is passed onto the respective WPs. WP2 will experiment on small samples with 3-9 mm for testing the fundamental behavior of new B-X phases and particularly as a feedback for binder matrix improvement. In WP3 samples (12 mm ) will be investigated from individual HPHT runs for characterization and testing to guide high pressure sintering process optimization. The HPHT process and the samples produced are then upscaled to the industrial mass production level in WP4. In WP5, demonstrator cutting tools from full size HPHT synthesis test runs will be prepared via laser cutting and consecutive macro- and microshaping of tool geometry within WP5. In WP6 aspects of environmental benefits in the total life cycle of the superhard materials will be investigated, including health and safety aspects. WP7 will focus on exploitation and dissemination.

The present invention relates generally to double-sided turning inserts for turning operations and, more particularly, to indexable double-sided turning inserts for turning operations and a turning tool. A double-sided turning insert (21) is provided with cutting edges (371) at alternating corners on opposite sides (41, 43) of the insert. Chipbreaker structures (451) can be provided without interfering with providing large supporting surfaces. When the insert is used in a cutting operation, chips from one of the cutting edges in use are unlikely to damage cutting edges that are not in use but are on adjacent corners.


A double-sided milling insert (30;30) for high feed milling of metal workpieces with a trigonal basic shape and comprising upper (31) and lower (32) faces facing in opposite directions and convex clearance surfaces (33) extending between the upper (31) and lower (32) faces. Each one of the faces comprises a recessed support surface (34A,34B), the support surfaces (34A,34B) being substantially parallel to each other, and having a cavity (35) therein for receiving a fastening means. Intersections of the convex clearance surfaces (33) with the upper and lower faces (34A,34B) form convex cutting edges (37A,37B;37A,37B) when seen in a plan view (fig. 1A) and a rake face (38) is provided adjacent the convex cutting edges (37A,37B,37a,37b). Each convex cutting edge (37A,37B,37a,37b) is concave when seen in a side view (fig. 1b) and comprises a substantially straight cutting edge portion (39A,39B;39A,39B) on each side of a curved cutting edge portion (40A,40B;40A,40B) when seen in a plan view (fig 1a). A milling tool with a plurailty of such inserts and a method of high feed milling using this tool are also disclosed.
