An apparatus and corresponding method for machining at least one spline in an aeronautical component. The apparatus comprises a holder defining an axial direction about which the holder is moveable, and a cutting insert attachable to the holder. The apparatus further comprises a coupling for attaching the cutting insert to the holder about a second direction that is perpendicular to the axial direction of the holder. The holder may comprise a first alignment feature for orientating the cutting insert at a single orientation with respect to the holder. The cutting insert may comprise at least one cutting tooth, wherein each cutting tooth comprises a cutting edge. The cutting insert may comprise a first datum surface which is spaced from each cutting edge by a respective predetermined spacing.

A machining tool includes a tool carrier with at least one seat receiving an exchangeable, indexable cutting insert. A fastening screw fastening cutting insert to seat has a head section for support on the cutting insert and a shaft section at least regionally having an external screw thread. The seat has a contact face supporting an underside of the cutting insert and at least one lateral bearing face supporting a side surface of the cutting insert. A through-hole is formed in the contact face, through which the shaft portion of the fastening screw extends. A clamping element is disposed on the tool carrier on the rear side of the contact face of the seat, in which an internal screw thread is formed, cooperating with the external screw thread of the fastening screw. The fastening screw and the clamping element can be jointly displaced in a displacement direction.

A toolholder has a plurality of receptacles for at least one respective cutting insert. For each receptacle, the toolholder comprises a clamping element associated with the receptacle and a hydraulic channel associated with the corresponding clamping element. Each clamping element is hydraulically adjustable between a closed position and an opened position via the associated hydraulic channel. Furthermore, the toolholder is configured such that the clamping elements in the closed position clamp the associated cutting inserts into the corresponding receptacle for the cutting operation and thus fix them to the toolholder and release them in the opened position so that the cutting inserts can be detached from the toolholder, in particular in a tool-free manner. Furthermore, a cutting tool is provided having a toolholder according to any one of the preceding claims and at least one cutting insert.

A cutting insert adaptor for an insert pocket can include one or more pairs of opposing insert abutment surfaces and pocket abutment surfaces which converge at an acute angle. The one or more insert abutment surfaces are all rotated in the same direction, relative to their paired pocket abutment surface which in turn rotates a cutting insert abutting the cutting insert adaptor relative to an orientation the cutting insert would have if it only abutted the insert pocket instead of the cutting insert adaptor.

An insert adaptor is configured for providing secure clamping of an insert in an insert pocket. The insert adaptor is configured to be located between an insert and an insert pocket and includes at least one magnetic surface configured for applying a magnetic attraction force to the insert pocket or a shim.

The present disclosure proposes an electrocaloric assisted internal cooling, texture turning tool and a nanofluid minimal quantity lubrication (NMQL) intelligent working system. The electrocaloric assisted internal cooling texture turning tool comprises an internal cooling turning tool handle, a direction-adjustable nozzle and an internal cooling turning tool blade; the internal cooling turning tool blade is arranged at one end of the internal cooling turning tool handle serving as a bearing device; an internal cooling turning tool pad is arranged between the internal cooling turning tool blade and a structure of the internal cooling turning tool handle bearing the blade; an internal cooling turning tool blade pressing device is further arranged on the internal cooling turning tool handle; the internal cooling turning tool blade is tightly pressed on the internal cooling turning tool handle by the internal cooling turning tool blade pressing device.

A cutting insert includes an insert peripheral surface that includes at least one planar major insert side abutment surface and an insert lower surface that includes an anti-slip recess recessed therein. The anti-slip recess includes at least one elongated and straight anti-slip groove. Each major insert side abutment surface is oriented parallel to a groove longitudinal axis of a respective anti-slip groove. An insert holder includes a holder pocket. The holder pocket includes a pocket peripheral surface which includes planar major pocket side abutment surface and a pocket base surface having an elongated and straight anti-slip rib. When the cutting insert is releasably attached to the insert holder, to constitute a fastened position of a cutting tool, the anti-slip rib is located in the anti-slip groove that is oriented parallel to the major insert side abutment surface that abuts the major pocket side abutment surface.

A cutting tool fastener having a rotation axis and configured to secure together, and establish a fluid path between, two cutting tool members, while also accommodating angular and pivotal displacement between the two. The fastener comprising a head with at least one head opening for emitting fluid, and a body which extends from the head and has a body opening for receiving fluid to be emitted via the head opening. The head has a spherical head abutment surface with a bottom spherical seal surface zone. At least a portion of the spherical head abutment surface faces the body, and the head opening opens out to the spherical head abutment surface. The bottom spherical seal surface zone is axially located between the body and the head opening.
