摘要： A method to form a surface on a metal work piece includes providing a turning insert having a first cutting edge, a second cutting edge and a convex nose cutting edge connecting the first and second cutting edges, a nose angle formed between the first and second cutting edges being less than or equal to 85°; arranging the second cutting edge such that it forms a back clearance angle of more than 90° in a feed direction; positioning all parts of the turning insert ahead of the nose cutting edge in the feed direction; rotating the metal work piece around a rotational axis in a first direction; and moving the turning insert in a direction parallel to or at an angle less than 45° relative to the rotational axis, such that the surface at least partly is formed by the nose cutting edge.

摘要： In order to perform turning operations of the kind that has heretofore been performed by diamond-shaped inserts, an insert which is basically equilateral triangular in shape with multiple alternately usable cutting edges, of which all three corners are usable as cutting edges, without decreasing the positional accuracy of the cutting edge during cutting. At least one recess and a plurality of protrusions are formed on each side of the insert. The recess and protrusions formed on the insert are brought into engagement with a protrusion and recesses formed on a side wall of a seating groove formed in a holder. In this state, the insert is pressed against a bottom seating face and the side wall of the seating groove with a clamp as a means to stably restrain the insert. This prevents shifting of the cutting edge during cutting even if the direction of the cutting force changes.
摘要翻译：为了执行迄今为止由菱形插入件进行的那种的转动操作，具有多个可交替使用的切削刃的基本上为等边三角形的刀片，其中所有三个角都可用作切削刃，而不减少切割时刀刃的位置精度。在插入件的每一侧上形成至少一个凹部和多个突起。形成在插入件上的凹部和突起与形成在保持器中形成的安置槽的侧壁上的突起和凹部接合。在这种状态下，插入件用夹具压靠在底座和底座的侧壁上，作为稳定地限制插入件的装置。这样即使切削力的方向发生变化，也能够防止切削时的切削刃的移位。

摘要： A cutting insert includes a body having three vertices, an upper face, a lower face, and six planar flank faces perpendicular to and joining the upper and lower faces. A cutting edge is formed at an intersection between the upper and lower faces and each of the planar flank faces. A triangular-shaped island surrounds a central axis, A, of the cutting insert and is higher in elevation than the upper and lower faces. A tool holder includes a tool holder body having an generally triangular-shaped insert-receiving pocket with a triangular-shaped recess that is substantially identical in shape to the triangular-shaped island of the cutting insert that interacts with the island to properly locate and prevent rotation of the cutting insert when mounted in the tool holder.

摘要： A boring bar has a shank having a cutter support head at one end. A flow passage extends to the cutter support head and intersects a transverse flow passage that is defined in part by a clamp screw passage of the head. A metal cutting insert is clamped to the cutter support head by a clamp that is secured by a clamp screw being threaded into the clamp screw passage. The clamp screw defines an internal or external passage that communicates with the internal coolant fluid passage and completes a coolant distribution circuit. The clamp defines an internal coolant fluid passage having a discharge opening located and oriented to direct a jet of coolant fluid onto the metal cutting insert immediately at the site of cutting engagement within the rotating workpiece. The cutter support head also has a passage and chip removal jet nozzle that orients a jet of coolant fluid adjacent the cutter insert for remove metal chips during machining.

摘要： A boring bar has a shank having a cutter support head at one end. A flow passage extends longitudinally through the shank to the cutter support head and intersects a transverse flow passage that is defined in part by a clamp screw passage of the head. A metal cutting insert is clamped to the cutter support head by a clamp that is secured by a clamp screw being threaded into the clamp screw passage. The clamp member defines at least one coolant fluid flow passage having a discharge opening or openings each located and oriented to direct a jet of coolant fluid onto the metal cutting insert immediately at the site of cutting engagement within the rotating workpiece. The clamp screw defines an internal passage that communicates with the transverse coolant fluid flow passage and conducts coolant fluid onto the metal cutting insert. Alternatively, an annular clearance is defined about the shank of the clamp screw and serves as a coolant flow passage which is in fluid communication with the internal coolant fluid discharge passage or passages of the clamp member.
