Description

A cutting insert and a cutting tool comprising such a cutting insert
TECHNICAL FIELD
The present invention relates to a cutting insert and to a cutting tool comprising such a cutting insert.
BACKGROUND
Within the cutting industry it is common to use a cutting tool comprising a toolholder with at least one replaceable cutting insert, having at least one cutting edge, mounted therein for performing a cutting process.
Cutting inserts used for processing a workpiece material, such as metal, are currently provided in a huge number of different variants with different properties such as materials and geometries. The suitability of a specific cutting insert for a specific process is highly dependent on its properties.
Cutting inserts with different properties may look very similar to each other for the human eye, which makes it difficult for an operator to decide whether a specific cutting insert is suitable for a specific process or not. In order to decide the properties of a cutting insert, the operator usually needs to find a serial or batch number provided on the cutting insert packaging and manually type this number in to an online catalog where its properties are listed.
This is a very time consuming work which also includes a lot of potential risk factors. For example, it is easy that an incorrect number is entered in the catalog which results in incorrect information being given to the operator. Another problem is that the original package of the cutting insert gets lost, which results in that the serial or batch number cannot be found. A further problem is that the catalog only provides general information on an insert type level. It does not provide specific information related to a unique individual cutting insert.
As a result, there is a risk that an unsuitable cutting insert is used for a specific process, which may result in a low quality of the workpiece processed by the cutting insert.
Attempts to solve this problem have been made by providing cutting inserts with unique identification markers in form of DataMatrix codes, which provide access to unique product information. Such a solution is disclosed in e.g. EP 3733332 Bl.
A problem with these solutions is that, during machining, the identification marker risks being worn out due to friction that arises between the cutting insert and the toolholder and/or the fastening element. As a result, the identification marker becomes unreadable, which results in a loss of the product information related to the cutting insert. SUMMARY OF THE INVENTION
It is an object of the present invention to overcome, or at least partly overcome, said problem by introducing a cutting insert and a cutting tool comprising such a cutting insert.
The object of the present invention is achieved by means of a cutting insert comprising a first main surface, a second main surface, and at least one side surface connecting the first main surface and the second main surface, wherein the cutting insert comprises a cutting edge, and wherein the cutting insert comprises at least one abutment surface configured to abut a support surface in a toolholder or a clamping surface at a fastening element, wherein the at least one abutment surface is arranged at any of the first main surface, the second main surface, or the at least one side surface, wherein the cutting insert further comprises a through hole extending from the first main surface to the second end surface, wherein the cutting insert further comprises at least one identification marker in form of a onedimensional or two-dimensional optical machine-readable code, wherein the at least one identification marker has a polygonal shape, wherein the at least one abutment surface comprises at least one recess comprising a bottom surface located a distance d from the abutment surface in a direction perpendicular to the abutment surface, and wherein the at least one identification marker is engraved or imprinted in the bottom surface.
By providing a recess in the abutment surface in which bottom surface the identification marker is engraved or imprinted, the identification marker is not coming in contact with the support surface in the toolholder or the clamping surface at the fastening element when the cutting insert is mounted in the toolholder. Thereby, the identification marker is protected from the friction that arises between the cutting insert and the toolholder and/or fastening element during machining. The risk of the identification marker being worn out is thereby reduced. Since the recess is arranged in the abutment surface, which will abut a support surface in the toolholder or a clamping surface at the fastening element during machining, the identification marker will be protected from wear caused by external impact, e.g. from generated chips, during machining.
A further benefit of arranging the at least one identification marker in a recess in the abutment surface, is that the manufacturing of the cutting insert is facilitated since postsintering operations, such as grinding, can be performed on the cutting insert with a reduced risk of damaging the identification marker.
The cutting insert is preferably a metal cutting insert for performing a metal cutting operation, such as milling, turning, drilling, boring or reaming.
According to an embodiment, the cutting insert is an indexable cutting insert.
By having the cutting insert being an indexable cutting insert, the lifetime of the cutting insert is improved.
According to an embodiment, at least one of the first main surface and the second main surface comprises a rake surface, and wherein the at least one side surface comprises a clearance surface, wherein the cutting edge is arranged at an intersection between the rake surface and the clearance surface. According to an embodiment, the cutting insert is a cubic boron nitride (CBN) cutting insert, a polycrystalline diamond (PCD) cutting insert, a cemented carbide cutting insert, a cermet cutting insert, or a ceramic cutting insert.
The fastening element can be any type of conventional fastening element, such as a screw, a clamp or a locking pin.
The term "one-dimensional or two-dimensional optical machine readable code" represent a passive identification marker that can be read by an optical reading device, e.g. a camera. The "one-dimensional or two-dimensional optical machine readable code" can be e.g. a Quick Response code, a High Capacity Colored Two Dimensional Code, a European Article Number code, a DataMatrix code, or a MaxiCode.
The at least one identification marker preferably comprises unique identification information, such as a unique identification number, of the cutting insert.
The recess is either provided in the abutment surface prior to sintering of the cutting insert by e.g. pressing, milling or laser processing, or post sintering of the cutting insert by e.g. milling, laser processing or spark-erosion cutting.
According to an embodiment, the identification marker is engraved in the bottom surface by use of a laser.
According to an embodiment, the bottom surface is parallel to the abutment surface.
By having the bottom surface arranged parallel to the abutment surface, the readability of the identification marker is facilitated. Also, the engraving or imprinting of the identification marker is facilitated.
Alternatively, the bottom surface is slightly inclined towards the abutment surface.
According to an embodiment, the at least one identification marker has an outer periphery, wherein the area within the outer periphery has an area Ai, and wherein the bottom surface has an area A2, wherein A2 = Ai.
By having the area of the bottom surface being equal to the area of the area within the outer periphery of the identification marker, the size of the recess can be kept at a minimum, which reduces the impact on the rigidity of the cutting insert and on the stability in the mounting of the cutting insert in the toolholder.
According to an embodiment, the recess has a cross-sectional area A2 as seen in a plane parallel to the abutment surface, wherein the cross-sectional area A2 is constant over the whole distance d.
By having the cross-sectional area of the recess constant over the whole distance d, the volume of the recess is kept to a minimum which reduces the impact on the rigidity of the cutting insert and on the stability in the mounting of the cutting insert in the toolholder.
Alternatively, the cross-sectional area A2 decreases towards the bottom surface. According to an embodiment, the abutment surface comprises a normal A extending in a direction perpendicular to the abutment surface, and wherein the bottom surface comprises a normal B extending in a direction perpendicular to the bottom surface, wherein the normal B coincides with the normal A.
By having the normal B coinciding with the normal A, the readability of the identification marker is facilitated. Also, the engraving or imprinting of the identification marker is facilitated.
According to an embodiment, the recess has a maximum cross-sectional area A3 as seen in a plane parallel to the abutment surface, and wherein the abutment surface has an area A4 as seen in a plane parallel to the abutment surface (110,112), wherein A4 > 3*A3.
By having the maximum cross-sectional area of the recess being smaller that the area of the abutment surface, the impact of the recess on the rigidity of the cutting insert and on the stability in the mounting of the cutting insert in the toolholder is reduced. A high quote between the area of the abutment surface and the maximum cross-sectional area of the recess reduces the impact of the recess on the rigidity of the cutting insert and on the stability in the mounting of the cutting insert in the toolholder.
According to an embodiment, the cutting insert comprises a central plane P extending midway between the first main surface and the second main surface, and wherein the cutting insert comprises a central axis C extending between the first main surface and the second main surface perpendicular to the central plane P, wherein the cutting insert has a two-fold rotational symmetry around the central axis C.
By having a two-fold rotational symmetry of the cutting insert around the central axis C, the risk of unbalances in the cutting insert is reduced.
According to an embodiment, the at least one identification marker comprises a plurality of first type modules and second type modules, wherein each first type module is in level with the bottom surface, and wherein each second type module comprises an indention with respect to the bottom surface.
By having the first type modules being in level with the bottom surface and the second type modules comprising an indention with respect to the bottom surface, a good contrast between the first type modules and the second type modules is achieved, which improves the readability of the identification marker. By having only the second type modules comprising an indention with respect to the bottom surface, the amount of material removal in the cutting insert is reduced compared to the case where both the first and second type modules comprise indentions relative the bottom surface. The identification marker's impact on the rigidity of the cutting insert and on the stability in the mounting of the cutting insert in the toolholder is thereby kept to a minimum.
According to an embodiment, the identification marker comprises a plurality of first type modules and second type modules, wherein each first type module comprises a first indention with respect to the bottom surface, wherein the first indention has a depth e, and wherein each second type module comprises a second indention with respect to the bottom surface, wherein the second indention has a depth f, wherein e * f.
According to an embodiment, the bottom surface comprises a normal B extending in a direction perpendicular to the bottom surface, and wherein the recess has a two-fold rotational symmetry around the normal B.
By having the recess having a two-fold rotational symmetry around the normal B, the risk of the recess introducing unbalances in the cutting insert is reduced. The impact of the recess on the stability in the mounting of the cutting insert in the toolholder is thereby reduced.
According to an embodiment, the recess has a four-fold rotational symmetry around the normal B.
By having the recess having a four-fold rotational symmetry around the normal B, the risk of the recess introducing unbalances in the cutting insert is even further reduced.
According to an embodiment, the recess has a square shape as seen in a plane parallel to the abutment surface.
According to an embodiment, d is in the range of 20-200 pm, preferably 50-150 pm, and more preferably 75-125 pm.
By providing a recess having a shallow depth, the recess will have an insignificant impact on the rigidity of the cutting element and on the stability in the mounting of the cutting element in the toolholder. However, the depth should not be too shallow since the identification marker will then not be protected from the friction generated between the cutting element and the toolholder and/or fastening element.
According to an embodiment, the bottom surface is a planar surface.
By having the bottom surface being a planar surface, the readability of the identification marker is improved. Further, the process of engraving or imprinting the identification marker in the bottom surface is facilitated.
Alternatively, the bottom surface can be slightly convex or concave.
According to an embodiment, the abutment surface is a planar surface.
By having the abutment surface being a planar surface, the stability in the mounting of the cutting insert in the toolholder is improved.
The object of the present invention is further achieved by means of a cutting tool comprising:
-a toolholder;
-a cutting insert as described above; and
-a fastening element having a clamping surface, wherein the toolholder comprises an insert pocket for receiving the cutting insert, wherein the insert pocket comprises at least one support surface, wherein the cutting insert is secured in the insert pocket by the fastening element, and wherein the at least one abutment surface abuts the at least one support surface, or the clamping surface.
By providing a recess in the abutment surface in which bottom surface the identification marker is engraved or imprinted, the identification marker is not coming in contact with the at least one support surface in the insert pocket, or the clamping surface at the fastening element when the cutting insert is mounted in the insert pocket. Thereby, the identification marker is protected from the friction that arises between the cutting insert and the toolholder and/or fastening element during machining. The risk of the identification marker being worn out is thereby reduced.
The cutting tool is preferably a metal cutting tool, such as a milling tool, a turning tool, a drilling tool, a boring tool or a reaming tool.
The fastening element can be any type of conventional fastening element, such as a screw, a clamp or a locking pin.
The insert pocket preferably comprises a bottom support surface, and at least one side support surface.
According to an embodiment, the recess is closed by the at least one support surface or the clamping surface.
By having the recess closed by the at least one support surface or the clamping surface, the identification marker engraved or imprinted in the bottom surface will be protected from wear caused by external impact, e.g. from generated chips, during machining.
According to an embodiment, the at least one abutment surface abuts the at least one support surface, wherein the at least one support surface is a planar surface, and wherein the abutment surface is a planar surface.
By having both the abutment surface, and the at least one support surface being planar surfaces, the stability in the mounting of the cutting insert in the insert pocket is improved.
According to an embodiment, the at least one abutment surface abuts the clamping surface, wherein the clamping surface is a planar surface, and wherein the abutment surface is a planar surface.
By having both the abutment surface, and the clamping surface being planar surfaces, the stability in the mounting of the cutting insert in the insert pocket is improved.
