    [0001] The subject of the present application refers to a chip control arrangement for a cutting insert. Such an arrangement can be formed in an insert configured for, among others, machining operations.
    BACKGROUND OF THE INVENTION
    [0002] Cutting inserts can be provided with a chip control arrangement to control the flow and / or control the shape and size of the chip and debris that result from metalworking operations.
    [0003] Such chip control arrangements usually consist of recesses and / or projections positioned close to a cutting edge of the insert. Upon finding the recesses and / or projections, metal shavings can be created with specific shapes and can then be evacuated from them.
    [0004] Various chip control arrangements are set out in US 5,758,994, US 4,720,217, US 5,282,703, US 5,476,346, US 7,976,251 JP 2007260848, JP 2008073827, US 5,577,867 and US 5,758. 994.
    [0005] It is an objective of the present application to provide a new chip control arrangement for a cutting insert.
    SUMMARY OF THE INVENTION
    [0006] According to the subject of the present application, a cutting insert is provided comprising a corner formed with a chip control arrangement comprising at least one projection which is elongated.
    [0007] For example, such a cutting insert may comprise:
    [0008] opposite upper and lower ends and at least first and second side surfaces extending between them,
    [0009] a first insert corner comprising a corner cutting edge formed at an intersection of the first and second side surfaces and the upper end, and
    [00010] a chip control arrangement in the first insert corner;
    2/13
    [00011] the chip control arrangement comprising
    [00012] a first projection which is elongated and arranged at the upper end adjacent to the intersection, and which extends longitudinally along the first lateral surface.
    [00013] The cutting insert may have at the upper end: a support that extends along the intersection, a cavity evacuation surface, and a chip deflection surface that extends between the support and chip evacuation surface; and wherein at least a major part of the first projection is positioned on the chip deflection surface.
    [00014] The upper and lower ends can be specularly symmetrical.
    [00015] The corner cutting edge can have a radius of curvature R and subtend a corner angle 0, where 80 ° <0 <100 °.
    [00016] The support can have a support width that can be variable. The support width can satisfy the condition 0.25 mm <W L <= 0.36 mm. The support can have a maximum support width that can be positioned between the first projection and the first lateral surface. The support can decrease in height with increasing distance from an associated lateral surface at a predetermined angle of support to, where 8 o <to <12 °.
    [00017] The first projection can comprise first and second ends and an intermediate portion between them. Each of the first and second ends may be closer to the respective associated side surface, respectively, than the intermediate portion. The first and second ends can generally be perpendicular to the intermediate portion and extend in the direction towards the associated lateral surface therefrom. The first projection can be spaced from the support. The first projection can each have a length L P , where 0.82 mm <L P <1.42 mm. The first projection can each have a projection width W P , where 0.09 mm <W P <0.49 mm. The projection length
    3/13 can be larger than the projection width. The first projection can comprise a projection peak, and in relation to an upward direction, a lower point of the support can be positioned higher than the projection peak. Each projection peak can be spaced from a cutting edge plane by a projection peak distance D P , where 0.95 mm <D P <1.05 mm.
    [00018] The chip control arrangement may comprise a second projection. The second projection can be elongated and arranged on the upper end adjacent to the intersection and can extend longitudinally along the second lateral surface. The second projection can have any of the characteristics defined above or below with respect to the first projection. Mentioned differently, the first and second projections can be identical.
    [00019] The first and second projections can be arranged symmetrically around the intersection.
    [00020] The cutting insert can comprise a plurality of corners, each of which can comprise a chip control arrangement identical to the chip control arrangement described above.
    [00021] The cutting insert may further comprise a central island which may comprise an elongated nose portion directed in the direction to the intersection. Each of the said trim control arrangements can be associated with a single nose portion of a central island.
    [00022] The chip control arrangement has been found to be advantageous for cutting cutting inserts, in particular for working with stainless steel. However, such chip control arrangements could possibly be advantageous for other types of operations, such as, for example, milling.
    [00023] It is understood that the aforementioned is a summary, and a cutting insert according to the subject of the present application can
    4/13 understand any of the characteristics above and below.

    DETAILED DESCRIPTION OF THE INVENTION
    [00035] In the following description, various aspects of the subject of the present application will be described. For explanatory purposes, specific settings and details are set out in sufficient detail to provide an in-depth understanding of the subject matter of this application. However,
    5/13 it will be apparent to a person specialized in the art that the subject of this application can be practiced without the specific configurations and details presented here.
    [00036] Attention is first given to figures 1 to 3, showing a cutting insert 20 with a chip control arrangement 60.
    [00037] The cutting insert 20 comprises opposing upper and lower ends 22, 24 and at least first and second side surfaces 26A, 26B extending between them.
    [00038] The chip control arrangement 60 comprises at least one first projection 28, 128, which is elongated and can be associated with a central island 32, or at least an elongated nose portion 34 thereof. The chip control arrangement 60 may further comprise a second projection 30, 130, which is elongated and disposed at the upper end 22 adjacent to intersection 56. The second projection 30, 130 can extend longitudinally along the second side surface 26B. The second projection 30, 130 can have any of the characteristics defined below with respect to the first projection 28, 128. With two projections 28, 128, 30, 130, the cutting insert 20 can be manipulated from the left and the right. As seen in the figures, the first projection 28, 128 and the second projection 30, 130 are on opposite sides of a corner bisector B and are partially spaced from it.
    [00039] In this non-limiting example, as shown in the plan view of the upper end 22 in figure 2, the cutting insert 20 has first, second, third and fourth side surfaces 26A, 26B, 26C, 26D, which are connected to the first, second, third and fourth corners 44A, 44B, 44C, 44D. More precisely, in such a view, the side surfaces 26A, 26B, 26C, 26D have a parallelogram shape and, even more precisely, a rhomboid. It is understood, however, that the chip control arrangement 60 described hereinafter could also be formed into inserts comprising a
    6/13 different number of sides or, in such a view, other formats comprising at least one corner.
    [00040] It is also observed that, in this non-limiting example, the cutting insert 22 is formed with a fixing hole 52 positioned in its center (in a flat view of the upper end 22), which opens towards the upper and lower ends bottom 22, 24 and is configured to receive a clamping element (not shown) through it. It is understood that alternative methods of fixing an insert in an insert holder could be used, for example, clamping jaws, and, therefore, such inserts could be devoid of a fixation hole 52.
    [00041] A central axis C extends through the upper and lower ends 22, 24. In this non-limiting example, the central axis C is coaxial with the fixing hole 52, and each of the first, second, third and fourth side surfaces 26A, 26B, 26C, 26D extend between the upper and lower ends 22, 24 in a direction parallel to the central axis C. References made hereafter to height are measurable along the central axis C. Additionally, as shown in figure 3 , the central axis C defines upward and downward directions Du, D d .
    [00042] A corner cutting edge 54 is formed at an intersection 56 of the first and second side surfaces 26A, 26B and the upper end 22. In this non-limiting example, the corner cutting edge 54 may belong to the cutting edge peripherally extending peripherally along the entire upper end 22, i.e., away from the intersection of the first and second side surfaces 26A, 26B and also along the third and fourth side surfaces 26C, 26D. However, it is understood that it would be sufficient for the corner cutting edge 54 to extend only on one or more cutting insert corners. While, in this non-limiting example, the cutting insert 20 is double-sided with each of its eight corners being formed with an identical chip control arrangement 60 and the upper and lower ends.
    Lower 7/13 22, 24 being specularly symmetrical around a plane of specular symmetry M that is perpendicular to the central axis C and extends through the first and second side surfaces 26A, 26B, is sufficient for the description hereinafter only refer to the corner cutting edge 54 in the first corner 44A. It is also understood that a cutting insert according to the subject of the present application could comprise one or more corners with such a chip control arrangement 60 and one or more other corners that are devoid of any chip control arrangement or that are formed with a different chip control arrangement. To elaborate, for example, the chip control arrangement 60 could be developed with any number of corners of a cutting insert 20 (for example, only at opposite diagonal corners 44A, 44C), and / or at two of its ends ( for example, at one or more corners at both the upper end 22 and the lower end 24) in a case where an insert is double-ended.
    [00043] With reference now to the top end flat view 22 in figures 4 and 5, the corner cutting edge 54 at the first corner 44A of the cutting insert 20 can be curved to a predetermined radius of curvature R. In this non-limiting example , the corner cutting edge 54 subtends a corner angle 0 of 80 °. that is, the corner cutting edge 54 follows an arc of 80 ° having a radius of curvature R. In another non-limiting example, the corner cutting edge 54 subtends a corner angle 0 of 100 °. It is understood that the corner cutting edge 54 having a radius of curvature R subtends a corner angle Θ that satisfies the condition 80 ° <0 <100 °.
    [00044] A support 58 can extend along the intersection 56. The support 58 can reinforce the corner cutting edge 54. The support 58 can further comprise, in a plane view of the upper end 22, a convexly shaped inner edge 62 The support 58 can have a width
    8/13 of support W L , which, in a plan view of the upper end 22, extends from an associated side surface 26A and in a direction perpendicular thereto. The support width W L can be variable. For example, the support 58 can have a minimum support width W L ie a maximum support width Wl2 · The minimum support width W L i can be positioned in a corner 44A of the cutting insert 20. The minimum support width W L i can have a value of 0.25 mm. The maximum support width W L2 can be positioned between the first projection 28 and an associated side surface 26A. More precisely, the maximum support width W L2 can be positioned between an intermediate portion 82 of the first projection 28 and the associated side surface 26A. The maximum support width W L2 can be 0.36 mm. It is understood that, although a preferred range for the support width Wl satisfies the condition 0.25 mm <W L <= 0.36 mm, values outside this range are also possible. Referring now to figures 6 and 7, the support 58 follows a straight line when viewed along a cross section thereof that is perpendicular to an associated side surface 26A. The support 58 can be tilted. In this non-limiting example, the support 58 decreases in height with increasing distance from an associated side surface 26A at a predetermined support angle α formed between the support 58 and a cutting edge plane Pce perpendicular to the central axis C and intercepting a IPce intersection point of the first and second side surfaces 26A, 26B and the upper end 22.
    [00045] The support angle α can be variable at different points along the length of the support 58. For example, the support angle α can have a minimum support angle a! and a maximum support angle of 2 .
    [00046] The minimum support angle cq can be positioned at a point along the support 58 adjacent to one of the first and second projections 28, 30. The minimum support angle cq can have a value greater than or equal to 8 o . The minimum support angle cq can be less than or
    9/13 equal to 10 °. It is understood that the range for the minimum support angle cq satisfies condition 8 o <cq <10 °.
    [00047] The maximum support angle at 2 can be positioned at a point along the support 58 spaced from the first and second projections 28, 30. The maximum support angle at 2 can have a value greater than or equal to 10 °. The maximum support angle at 2 can be less than or equal to 12 °. In this non-limitative example, the minimum support angle cq has a value of 9 o and the maximum support angle a2 has a value of 1 I o . It is understood that the range for the maximum support angle a2 satisfies condition 9 o <to 2 <11 °.
    [00048] Returning to figure 2, a chip evacuation surface 64 can be positioned at the top end 22 and is spaced from the support 58. The chip evacuation surface 64 is configured to evacuate chips (not shown) away from the corner cutting edge 54. In this non-limiting example, the chip evacuation surface 64 can be flat and can extend perpendicular to the central axis C, although, in other examples, the chip evacuation surface 64 can be not flat.
    [00049] A chip deflection surface 66 can extend between support 58 and chip evacuation surface 64. The chip deflection surface 66 is configured to deflect and direct metal debris (not shown) created through an operation metal workpiece, towards the chip evacuation surface 64.
    [00050] The central island 32 can extend from the chip evacuation surface 64 in a direction towards the central axis C. The central island 32 can be surrounded by the chip evacuation surface 64. More precisely, in this example non-limiting, the central island 32 extends between the chip evacuation surface 64 and the fixing hole 52, and can surround the latter. The center island 32 may extend higher than the chip evacuation surface 64.
    10/13
    [00051] The elongated nose portion 34 of the central island 32 can be directed in the direction to an associated intersection 56. The central island 32 can comprise a plurality of elongated nose portions 34, each of which is associated with, and directed in the direction to, an associated intersection 56. In a plan view of the upper end 22, each elongated nose portion 34 can be connected by a convexly curved island connecting portion 70. The central island 32 can comprise an inner portion 72, the which, in this non-limiting example, is positioned between the nose portions 34 and the fixing hole 52. The innermost portion 72 can be flat. The innermost portion 72 can be of a height D ( (figure 7) above the cutting edge plane P C e- In this non-limiting example, the height D, can be 0.14 mm.
    [00052] With reference now to figures 4 to 8, the first and second projections 28, 128, 30, 130 are configured to cause metal debris to form chips with desired shapes and sizes and to facilitate their evacuation from the area cutting. More precisely, at least a major part of the first and second projections 28, 30 can extend from the chip deflection surface 66 and protrude from it. A smaller portion of the first and second projections 28, 30 can be partially positioned on the chip evacuation surface 64. The first and second projections 28, 128, 30, 130 can be arranged symmetrically around corner bisector B in the intersection 56 or associated corner 44A. Since the first and second projections 28, 128, 30, 130 are identical, the following description will refer to only the first projection 28, 128, for brevity, with an understanding that the same is true for the second projection 30 , 130.
    [00053] The first projection 28, 128 extends longitudinally along an associated lateral surface 26A. The first projection 28, 128 can extend between adjacent corners 44A, 44D. In this non-limiting example, in a plan view of the upper end 22, the first / 13 projection 28, 128 may have a concave curved shape. More precisely, in such a view, the first and second ends 78, 80 of the first projection 28, 128 may be closer than the intermediate portion 82 thereof to an associated side surface 26A. With reference now to Figure 9, the first and second ends 78, 80 can generally be perpendicular to the intermediate portion 82 and extend in a direction of the first side surface 26A therefrom. It will be understood that although the first projection 28, 128 may be curved, with the intermediate portion 82 being only slightly curved, it can still be considered to extend or be elongated in a direction mainly defined by the intermediate portion 82. Thus, for example, the first projection 28, 128 can be considered to extend from its intermediate portion 82, in opposite directions, in the direction to adjacent corners 44A, 44D. It is further observed that the ends 78, 80 of each elongated portion define a projection length L P of the first projection 28 along the associated side surface 26A between adjacent corners 44A, 44D. The projection length L P may correspond to, and coincide with, a length of a curved portion of the chip deflection surface 66, on which the associated projection is positioned. Similarly, the ends 78, 80 of each elongated portion may correspond to limits of the convexly shaped inner edge of the support 62. Put differently, a length of the convexly shaped inner edge of the support 62 can have a magnitude identical to the magnitude of the projection length L P.
    [00054] The first projection 28 can be arranged closer to an associated corner 44A than to an intermediate point P of an associated side surface 26A. More precisely, the first projection 28 can be positioned within the third part closest to an imaginary division of the upper end 22 which extends from the second side surface
    12/13
    26B at the first corner 44A and extending to the intermediate point P of the side surface 26A. Even more precisely, if such an imaginary division comprised six equal parts, the first projection 28 would be positioned in the second part from corner 44A.
    [00055] With reference to figure 5, the first projection 28 can be connected to the chip evacuation surface 64 in a connection area designated as 84. The first projection 28 can be spaced from the support 58. The first projection 28 has the projection width W P taken in a direction perpendicular to the projection length L P , where the projection length L P is greater than the projection width W P , that is, L P > W P. The projection length L P of the first projection 28 can have a magnitude of at least three times the maximum magnitude of the projection width W P , i.e., L P > 3 W P. For example, the projection length L P can have a value of 1.12 mm and the maximum projection width W P can have a value of 0.29 mm. In other examples, the projection length L P can have values between 0.82 mm and 1.42 mm and the maximum projection width W P can have values between 0.09 mm and 0.49 mm.
    [00056] With reference now to figure 7, and in relation to the upward direction Du, even a lower point 86 of the support 58 (i.e., a point 86 further from the side surface 26A) is positioned higher than one projection peak 68 from the first projection 28. In addition, the projection peak 68 from the first projection 28 is distanced from the cutting edge plane Pce by a projection peak distance D P. The peak projection distance D P can be greater than or equal to 0.95 mm. The peak projection distance D P can be less than or equal to 1.05 mm. In this non-limiting example, the peak projection distance D P is 0.1 mm. It is understood that the range for the peak projection distance D P satisfies the condition 0.95 mm <D P <1.05 mm.
    [00057] It is understood that the trim control arrangement according to
    13/13 the subject of the present application may be exempt from additional elements to obtain the desired chip control. Put differently, a chip control arrangement according to the subject of the present application may comprise exactly / only two projections. In other words, the chip control arrangement can be devoid of any additional projections. Additionally, the chip control arrangement or a corner of a cutting insert having the same can be associated with a single nose portion of a central island.
    [00058] Although the subject matter of this application has been described by a certain degree of particularity, it should be understood that various changes and modifications could be made without departing from the spirit or scope of the subject matter as claimed hereinafter. For example, while ranges, values and element locations, for example, described above, have been found to be an advantageous configuration for inserts for metering, particularly for working with stainless steel, other ranges, values and element locations for different types of operations and / or workpiece materials are also possible.
