Abstract
A tool intended for chip removing machining includes a holder and a cutting insert which have respective connecting surfaces arranged to engage each other and define an interface. A ridge having a tapering cross-sectional shape is formed in one of the connecting surfaces, and a groove having a tapering cross-sectional shape is formed in the other connecting surface, which groove receives the ridge. Both of the ridge and groove are in the shape of curves as viewed in a direction perpendicular to the respective connecting surface. The curve shape may be circular, elliptical, or polygonal.

Tool for chip removing machining, comprising first and second parts, the first part including a top cutting side, a bottom side disposed opposite the top cutting side, and a peripheral side surface extending between the top and bottom sides;
- the second part including a seat on which the bottom side is mounted, wherein the bottom side and the seat define respective first and second connecting surfaces arranged to engage each other;
- a ridge formed on one of the connecting surfaces and a groove formed in the other connecting surface, the groove receiving the ridge such that the groove and the ridge lie substantially in a plane oriented perpendicularly to a center axis of the first part, which center axis passes through the top and bottom sides;
- the ridge and the groove being tapered in a direction away from the top cutting side;
- each of the ridge and the groove being of curved shape within the plane, wherein the curvature of the ridge and the groove is visible when the ridge and the groove are viewed in a direction perpendicular to the plane.
Cutting insert for chip removing machining, comprising a body having a top cutting side, a bottom side disposed opposite the top side, and a peripheral side surface extending between the top and bottom sides, the bottom side defining a connecting surface adapted for interaction with an analogous connecting surface in a tool part, wherein the connecting surface comprises a groove tapered in a direction toward the top side;
- the groove lying substantially in a plane oriented perpendicularly to a center axis of the body which center axis passes through the top and bottom sides, the groove being of curved shape within the plane wherein the curvature of the groove is visible when the ridge is viewed in a direction perpendicular to the plane.
