Definitions
- the invention relates to a cutting plate for machining metal workpieces with at least one cutting edge delimited by a rake face and a free face, the rake face having a rake face section adjoining the cutting edge with a positive rake angle with respect to the cutting plane and several parallel to the cutting edge in Distance from each other, formed in the rake face section, delimited by its upper edge relative to the rake face section and partially penetrating the cutting edge, has dome-shaped recesses.
- the chip breakage and the chip removal during the cutting process can be promoted (DE-C-28 40 610).
- the chip receives a corrugated structure there during the cutting process and thus a greater rigidity, which is necessary for easier breaking. Small, broken chips are particularly important for undisturbed chip removal when drilling. This also requires a suitable deformation of the braced chip, which leads to a safe chip break.
- the object of the invention is Reasons to improve the known insert of the type mentioned in the introduction so that the formation of small, short-broken chips is favored during the machining operation.
- a chip-forming step is arranged on the side of the dome-shaped recesses opposite the cutting edge, which protrudes in the direction of chip travel over the rake face section containing the recesses, and that the rake face in the area of the rake face section positive and in the area of the recesses has a neutral or negative rake angle with respect to the plate plane.
- a particularly advantageous cutting and chip breaking behavior is achieved if the rake angle of the concave rake surface section is 15 to 25 ", while it is 0 to -10 'in the region of the recesses at the location of the cutting edge.
- the chip which is provided with a transverse wave structure, collides with the chip direction against the chip forming step and there is sharply deflected.
- the deflection leads to chip breaking, so that small, short broken chips are created.
- the chip-forming step can terminate tangentially into the rake face section at its boundary line on the cutting edge side, while it can merge sharp-edged into a central rake face plateau arranged above the cutting edge with respect to the cutting plate plane above the cutting edge at its boundary line away from the cutting edge.
- a preferred embodiment of the invention provides that the chip-forming step extends in a straight line or in a wave-like manner, essentially parallel to the cutting edge, and the dome-shaped recesses are tangent with their boundary line on the cutting edge side or are arranged at a distance therefrom.
- the chip-forming step on its cutting edge-side boundary line is curved so wavy and zigzag-shaped that it does not penetrate into the dome-shaped recesses, additional wedge effects occur in the spacing area between the recesses, which promote chip breakage.
- a further improvement in this regard can be achieved in that the chip-forming step with its boundary line on the cutting edge side engages in a wedge-shaped manner with the wedge tip facing the cutting edge in the dome-shaped recesses and forms the upper edge there.
- the chip forming step with its boundary line away from the cutting edge can be essentially in phase or in phase parallel to have a wave-shaped and / or zigzag-shaped course running along the edge of the cutting edge.
- a further advantageous embodiment of the invention provides that the dome-shaped designs form a conical dome-shaped hollow surface converging towards the cutting edge, penetrating the cutting edge, while they merge into a spherical dome-shaped hollow surface on the side of the chip-forming step.
- a further preferred embodiment of the invention provides that the rake face section between the cutting edge and the chip shaping step is curved concavely in the direction of chip removal, the chip shaping step between the rake face section and the rake face plateau connecting tangentially to the concave curved rake face section and also being able to be concavely curved.
- the recesses penetrating the cutting edge ensure that the corrugated sheet-like chip only strikes the chip-forming step at certain points, so that there is only little cutting resistance and little heat transfer from the chip to the cutting plate. It has proven to be particularly advantageous if the recesses, as cylindrical spherical caps penetrating the cutting edge, essentially with the free surface vertical cylinder axis are formed. In principle, it is also possible to design the recesses as conical spherical caps penetrating the cutting edge with the deepest generatrix substantially perpendicular to the free surface, or as elipsoid or paraboloid cathodes penetrating the cutting edges with their deepest generatrices essentially perpendicular to the free surface to train.
- the distance between the cutting edge and the boundary edge of the recesses on the plateau side is less than 50%, preferably 20 to 30%, of the distance between the cutting channel plateau edge on the cutting edge side.
- the cutting insert can be provided with a plurality of cutting edges delimiting a polygon and penetrated by dome-shaped recesses, while the delimiting and / or zigzag-shaped curved boundary lines of the chip-forming steps, if appropriate, have a corresponding circumferential distance from the cutting edges Can form polygon.
- the cutting edges in the area between the recesses adjacent to one another are partially chamfered. So that the same cutting ten can be used as the inner and outer plates of a solid drill, it is advantageous if the cutting edges in the corner region between the corner and only one of the adjacent recesses are almost asymmetrically.
- the cutting edges can be chamfered, if necessary, in continuation of the corner chamfers starting from the corner, in the area between the recess adjacent to the corner and the next and possibly the next but one recess.
- Figure 1 is a plan view of a trigonal cutting tip.
- FIG. 2a to i show an enlarged detail from FIG. 1 with nine different embodiments of the chip shaping steps;
- Fig. 3a shows a section along the section line A-A of Fig. 2e;
- 3b shows a section along the section line B-B of FIG. 2e
- 4a shows a modified embodiment of a trigon-shaped insert in a diagrammatic representation
- 4b is a plan view of the cutting insert according to FIG. 4a;
- FIG. 4c shows a section along the section line C-C of FIG. 4b;
- FIG. 4d and e show a view in the direction D and E of FIG. 4b in an enlarged sectional view.
- FIG. 5 shows a trigon-shaped cutting insert with asymmetrical corner chamfer in a representation corresponding to FIG. 4a.
- the cutting plates shown in FIGS. 1 and 4a are designed as hexagonal cutting inserts, the cutting edges 10 of which are alternately connected at the corners 12 and 14 by an acute corner angle 0 and an obtuse corner angle £.
- Such cutting inserts are used, for example, in solid drills, in which two cutting edges 10 separated by the obtuse corner angle bis as far as the neighboring corners 12 are effective in pairs.
- the cutting edges 10 are each formed by the transition between the rake face 16 and the adjacent free face 18.
- the rake face 16 is subdivided into a substantially flat surface section 20 near the cutting edge and a plateau 22 located higher up and away from the cutting edge, which are connected to one another in the chip removal direction by a chip shaping step 24.
- the chip forming step 24 goes tangentially into the surface section on its cutting line-side boundary line 26 20 over, while at its cutting line away from the cutting edge 28 it changes sharply into the plateau 22 (FIGS. 3a, b and 4c). In the center of the plateau area 22 there is an opening 23 for the passage of a fastening screw, not shown.
- the surface sections 20 and chip-forming steps 24 belonging to the individual cutting edges are connected to one another via the corners 12, 14 and form a continuous continuous surface or step.
- the rake face 16 there are in the area of the surface sections 20 along the cutting edges 10 side by side spaced-apart dome-shaped recesses 30 which extend to the cutting edge 10 and penetrate this in an edge section 32.
- the recess 30 in the region 34 near the cutting edge is designed to be converging in the shape of a spherical cap toward the cutting edge, while in the region 36 remote from the cutting edge it has the shape of a spherical cap.
- the trough-shaped depression 38 in the flat surface section 20, the depth of which is smaller than that of the dome-shaped recesses 30.
- the exemplary embodiments shown in FIGS. 2a to i differ from one another primarily in the shape of the chip shaping step 24.
- the chip shaping step 24 can either have the recesses 30, 38 on its inner boundary line 26 in a straight line parallel to the cutting edge 10 tangent (Fig. 2a) or at a small distance from these (Fig. 2b).
- the chip-forming step 24 can run in a wave-like and / or zig-zag manner on its boundary line 26 on the cutting edge side, in such a way that it tan the dome-shaped recesses 30 (FIGS. 2c, d, g, h) at a distance of these run (Fig. 2e) or intervene in sections in these (Fig. 2f and i).
- wedge formation in the area of the chip shaping step in the spacing area between the recesses 30 (FIGS. 2c, d, e and g) on the one hand or within the dome-shaped recesses 30 (FIGS. 2f, h and i) on the other hand achieves an additional break-promoting chip deformation.
- the plateau-side boundary line 28 of the chip-forming step 24 can either run in a straight line (FIGS. 2a, b, c, d, e, f) or in a wave shape (FIGS. 2g, h, i), the boundary lines 26, 28 in the latter case the chip shaping step 24 can be corrugated either in the same direction (FIG. 2g, h) or in the opposite direction (FIG. 2i).
- the rake face section 20 and the subsequent chip shaping step 24 are concave, tangentially merging into one another in the chip running direction.
- the rake angle oC with respect to the plate plane 40 is positive at the location of the cutting edge 10 and is approximately 15 to 20 '(FIG. 4e).
- the recesses 30 are designed as short cylindrical spheres penetrating the cutting edge 10 with a cylinder axis approximately perpendicular to the free surface 18.
- the plate level 40 is negative there and is approximately -5 '(FIG. 4e).
- the distance between the cutting edge 10 and the boundary edge of the recesses 30 on the plateau side is relatively small and is only about 20 to 30% of the distance between the cutting edge 10 and the plateau boundary line 28 on the cutting edge side.
- the cutting edges 10 are provided with a chamfer 42 with a chamfer angle f of approximately in the area between the recesses 30 adjacent to one another at corner 12 20 'opposite the plate plane 40 (Fig. 4a and d).
- the corner chamfers 42 are each arranged between the plate corner 12 and only one of the adjacent recesses 30, while the cutting edge 10 is formed with sharp edges between the corner 12 and the other recess 30.
- the chamfered corners point radially to the center of the drill and with their sharp-edged corners to the outside. In spite of the corner bevels, it is thus possible to use the same cutting inserts as the inner plate and as the outer plate of a solid drill without any loss in cutting quality.
- the invention relates to a cutting insert for the machining of preferably metallic workpieces.
- the cutting insert has at least one cutting edge 10 in the transition region between a rake face 16 and a free face 18, the rake face 16 having a planar surface section 20 which runs essentially parallel to the cutting edge 10 and a plurality of which are formed in the surface section 20 and are spaced apart parallel to the cutting edge 10 , the cutting edge 10 has partially penetrating dome-shaped recesses.
