摘要:
A cutting insert 2 includes an upper surface 6, a lower surface 7 on a side opposite to the upper surface 6, and a peripheral side surface 8 connecting the upper surface 6 and the lower surface 7. A cutting edge 61 is formed in at least a part of a first ridgeline 60 where the upper surface 6 and the peripheral side surface 8 intersect. At least one bottomed recess 10 recessed from the lower surface 7 to the upper surface 6 is formed in an outer peripheral portion of the lower surface 7. Each of the recesses 10 is formed in a substantially triangular shape having a first vertex P, a second vertex Q, and a third vertex R. The first vertex P and the second vertex Q are respectively positioned on a second ridgeline 70 where the lower surface 7 and the peripheral side surface 8 intersect. The third vertex R is positioned on the lower surface 7 and separated from the second ridgeline 70.
摘要:
A cutting edge configuration of a cutting tool for performing a cutting process on a surface (21) of a workpiece (19), the cutting tool including a rake face (3) provided with first and second cutting edges (11, 13), the cutting tool being moved relative to the surface-to-be-cut (21) with the first and second cutting edges (11, 13) cutting thereinto to thereby perform the cutting process, wherein the first cutting edge (11) is positioned ahead of the second cutting edge (13) in a cutting direction (z-direction) of the cutting tool to provide the rake face (3) with a feed-direction (y-direction) rake-angle, and the cutting tool is fed in a direction from a side of the second cutting edge (13) to a side of the first cutting edge (11).

The invention relates to a device (1) for processing preferably metal workpieces in a chip-removing manner, comprising a tool (2) and a workpiece holder (3), wherein the tool (2) can be moved in relation to a workpiece (4) accommodated in the workpiece holder (3) along a specifiable motion path in order to process the workpiece (4) in a chip-removing manner, wherein the tool (2) can be pivoted in relation to a workpiece (4) accommodated in the workpiece holder (3) about a tool pivot axis (W), wherein the tool pivot axis (W) is oriented at least substantially perpendicularly to the motion path, wherein the device is designed to correct the orientation of the blade (9) of the tool (2) in accordance with the course of the motion path by means of a pivoting of the tool (2) in relation to the workpiece (4) about the tool pivot axis (W). In order to present a method and a device that enable faster and thus more efficient production, the tool holder (8) is accommodated on an linear drive (10), which in turn is itself accommodated on a tool carrier (5) in such a way that the linear drive can be pivoted about a linear drive pivot axis (L).
