Abstract: A cutting insert wherein, in particular an indexable cutting insert for machining predominantly metal materials, comprising a first surface that acts as a contact surface for a chuck tool and a depression in the first surface in the cutting corner region and along the cutting edges, said depression acting as a swarf surface. To reinforce and stabilize the cutting edge, the first swarf surface border or the second swarf surface border has or have one or more interruptions in the form of ribs surface, said ribs lying on the same plane as the second surface.

Abstract: A negative insert has double-positive clearance surface.

Abstract: A cutting insert, that is chucked in carrier tools, comprising an upper and lower face, a cutting corner with a corner radius being located on each upper and lower face, a cutting corner with a corner radius being located on each upper and lower face, between a primary cutting edge and a secondary cutting edge. To reinforce the cutting corner, which is at risk from damage during insertion, while maintaining the corner radius in relation to a cutting insert according to prior art, a stabilizing facet is provided in the cutting corner adjacent to the corner radius.

Abstract: During the machining of workpieces, in particular dynamic loads act on the cutting tools in addition to the static loads. This leads to chipping at the cutting edges of the cutting elements and thus to the destruction of the cutting element with the possible consequence that the workpieces is damaged and thus becomes useless.

Abstract: Patterns detection to input data containing a plurality of transactions, each transaction having at least one item, is carried out in the following way. Filter conditions for interesting patterns are received, and a first wet of filter conditions applicable in connection with generation of candidate patterns is determined.
