The invention relates to a cutting plate for a chip-removing cutting tool, comprising a cutting plate top face and a cutting plate bottom face, one or more lateral faces, cutting edges at the transition between the cutting plate top face and the one or more lateral face, and a circular chip recess in the cutting plate top face that has an outside diameter d. In order to reduce the production costs, according to the invention the following applies to the outside diameter dof the chip recess: 2 mm&#x3c;d&#x3c;=6 mm, preferably 2 mm&#x3c;d&#x3c;5 mm.

Miniaturized cutting plate

A cutting tool has a recess for receiving a cutting insert having a clamping depression on the rake face. The cutting insert is held in the carrier tool by a clamping finger having a lug. The clamping finger being secured on the carrier tool via a clamping bolt so that when tightening the clamping bolt, the clamping finger pulls the cutting insert into the recess. A sickle-shaped engagement element engages into the clamping depression of the cutting insert being arranged on the lug. The clamping bolt has a clamping head overhanging its shank. The clamping head is seated on an angled locating surface of the clamping finger with respect to the axis of the clamping bolt, wherein said surface is arranged so compression force of the clamping finger on the cutting insert is enhanced. The lug has a clamping surface for bearing on the rake face of the cutting insert.

Cutting tool and cutting insert

The invention relates to a milling tool () having a length land diameter dand having blades () for the milling of mostly metal workpieces. In order to prevent an uncontrolled failure of the milling tool, it is proposed that the blades () are partially or entirely made of polycrystalline cubic boron nitride (PcBN) or polycrystalline diamond (PCD) and the diameter dof the milling tool lies between 7 mm and 40 mm.

Milling cutter for hard machining

The invention relates to an indexable insert () for fitting in supporting tools () for the machining of workpieces, with an upper side () and an underside (), on which clamping recesses are arranged, and with a circumferential geometry () joining the upper side () and the underside (), wherein cutting corners and cutting edges () are arranged at the transition from the upper side () and the underside () to the circumferential geometry (). In order that the clamping situation during machining is improved significantly, and at the same time the introduction of the clamping recesses is made easier, it is proposed that the clamping recess consists of grooves () which are arranged on two crossing straight lines (), wherein the two straight lines () run at right angles in relation to each other and all the grooves () are arranged at the same distance from the center axis or longitudinal axis () of the indexable insert (), and the crossing point () of the two straight lines () lies on the center axis or longitudinal axis () of the indexable insert ().

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.
