Abstract: A method and a corresponding system and computer program are provided. A model of an object to be manufactured via subtractive manufacturing is obtained. Geometric features to be machined as part of manufacturing the object are identified based on the model. The identified geometric features include a composite geometric feature including a plurality of geometric subfeatures. A database including strategies for machining different geometric features is accessed. The database includes a composite strategy for machining the composite geometric feature and separate strategies for machining the respective geometric subfeatures. Strategies for machining the respective geometric features are selected from the strategies included in the database. Instructions for causing one or more machine tools to manufacture the object in accordance with the selected strategies are provided.

Abstract: A cutting insert, intended for drills, in particular long hole drills, includes a cutting edge from which a concavely curved, chip removing surface extends up to a ridge where the curved surface transforms into a top side of the cutting insert. A number of long narrow chip-embossing formations (e.g., grooves or beads) extend from the chip removing surface to the top side with the purpose of producing, in the underside of the chip, long narrow embossments in the form of either ridges or flutes in order to stiffen the chip and make it more prone to breakage.

Abstract: An element which defines a support pad and/or a guide bar adapted to be mounted in a seat of a cutter head of a deep hole drill comprises a body which defines a longitudinal direction and a cross-direction. The body includes an inner mounting side and an opposing outer side. The outer side includes a contact surface which is adapted to engage a wall of a hole being drilled. The outer side also includes a countersink extending across the outer side in a direction transversely of the longitudinal direction. An edge of the contact surface facing toward a center of the body forms an angle with the longitudinal direction in the range of 55°±10°.
