DETAILED DESCRIPTION OF THE INVENTION
    The present invention relates to a reversible orientable cutting insert 20 having first and second opposite end surfaces 22 interconnected by a continuous peripheral surface 24, the peripheral surface 24 with at least three side surfaces 26 alternating with at least three surfaces of corner 28.
    [0015] In some embodiments of the present invention, the at least three side surfaces 26 can be identical, and the at least three corner surfaces 28 can be identical.
    [0016] As shown in Figs. 1 and 2a, the cutting insert 20 may have the basic shape of a regular polygon.
    [0017] In some embodiments of the present invention, the cutting insert 20 can preferably be manufactured by pressing and sintering a cemented carbide, such as tungsten carbide, and can be coated or uncoated.
    [0018] As shown in Figs. 3 and 4, the cutting insert 20 has a median plane M located between the first and second end surfaces 22 and intersecting the peripheral surface 24 to form an insert contour line Lb.
    [0019] In some embodiments of the present invention, the first and second end surfaces 22 may be identical, each having a support surface 30 substantially parallel to the median plane M.
    [0020] Also, in some embodiments of the present invention, the two support surfaces 30 can be equidistant from the median plane M.
    [0021] As shown in Figs. 3 and 4, the at least three lateral and corner surfaces 26, 28 may have median lateral and corner regions 32, 34, respectively, forming a continuous peripheral median region 36 extending perpendicular to the median plane M.
    [0022] Throughout the description, it should be appreciated that the perpendicularity of the peripheral median region 36 with respect to the median plane M has a manufacturing tolerance of 0.5 °.
    [0023] In some embodiments of the present invention, the peripheral median region 36 may show specular symmetry around the median plane M.
    Also, in some embodiments of the present invention, each lateral median region 32 can be flat.
    [0025] As shown in Figs. 1 and 2a, the cutting insert 20 has a geometric axis of insertionAl perpendicular to the median plane M around which the cutting insert 20 is orientable.
    [0026] In some embodiments of the present invention, the peripheral surface 24 may have exactly three side surfaces 26 alternating with exactly three corner surfaces 28, and the cutting insert 20 may have triple rotational symmetry around the geometric axis of insertAl .
    [0027] Also in some embodiments of the present invention, a through hole 38 coaxial with the insert geometric axisAl can extend between and open outward on both first and second end surfaces 22.
    [0028] As shown in Figs. 1 and 2a, the cutting insert 20 may have the basic shape of an equilateral triangle.
    [0029] In some embodiments of the present invention, the cutting insert 20 can be manufactured by direct pressing along the direction of the geometric axis of insertAl.
    [0030] Also, in some embodiments of the present invention, the cutting insert 20 can be pressed into its final shape, and the peripheral surface 24 can be unground.
    [0031] According to the present invention, the side and corner surfaces 26, 28 intersect with both the first and second end surfaces 22 at the side and corner edges 40, 42, respectively, with each side edge 40 having a main cutting edge 44, and each corner edge 42 having a corner and secondary cutting edge 46, 48.
    [0032] Thus, the cutting insert 20 is advantageously configured with two main cutting edges 44 per side surface 26, and two corner and secondary cutting edges 46, 48 per corner surface 28, and so for embodiments presenting triple rotational symmetry around the insert geometric axis, the cutting insert 20 has a total of six main, corner and secondary cutting edges 44, 46, 48
    [0033] In an end view of the cutting insert 20, as shown in Fig. 2b, each corner cutting edge 46 can be curved while the secondary and main cutting edges 44, 48 can be straight. Each curved corner cutting edge 46 extends between a first endpoint E1, where merges with a substantially straight portion of its associated main cutting edge 44, and a second endpoint E2, where it merges with a substantially straight portion of its associated secondary cutting edge 48.
    [0034] In a side corner view of the cutting insert 20, as shown in Fig. 3, each corner cutting edge 46 can again be curved while the secondary and main cutting edges 44, 48 can again be straight.
    [0035] As shown in Fig. 4, a lateral geometric axis A2 can extend transversely to each lateral surface 26, and each lateral surface 26 may have double rotational symmetry around its associated lateral geometric axis A2.
    [0036] In some embodiments of the present invention, each main cutting edge 44 can intersect a lateral bisector plane Ps containing the insert geometric axisAl and its associated lateral geometric axis A2. For these embodiments, it can be understood that each main cutting edge 44 extends over more than half the peripheral length of its associated lateral surface 26.
    [0037] According to the present invention, as shown in the side corner view of Fig. 3, each main and secondary cutting edge 44, 48 slopes outward from the first and second end points E1, E2, respectively , from its mutually associated corner cutting edge 46, towards the median plane M.
    [0038] In some embodiments of the present invention, each main and secondary cutting edge 44, 48 can tilt out from its mutually associated corner cutting edge 46 towards the median plane M along its entire length .
    [0039] Also, in some embodiments of the present invention, as shown in Figs. 3 and 5, each corner cutting edge 46 can be located entirely further away from the median plane M than each of the support surfaces 30.
    [0040] Furthermore, in some embodiments of the present invention, as shown in Fig. 6, each end surface 22 may include an inclined surface 50 adjacent to each main cutting edge 44, with each inclined surface 50 inclined towards to the median plane M and merging with its associated support surface 30.
    [0041] As shown in Figs. 2b and 5, a first imaginary straight line LI extending perpendicular to the median plane M and intersecting any of the corner cutting edges 46 at any point along its length except the second endpoint E2, passes through the median plane M within the insert contour line Lb.
    [0042] It should be appreciated that the first imaginary straight line LI appears as a point in an end view of the cutting insert 20, as shown in Fig. 2b.
    [0043] In a similar vein, as can be guessed from Figs. 1, 2a and 2b, in an end view of the secondary cutting edges 48 on the median plane M, (projection not shown) each secondary cutting edge 48 can be coincident with the insert contour line Lb.
    [0044] In some embodiments of the present invention, as shown in Fig. 3, each corner surface 28 may include two corner relief surfaces partially conically shaped 52 extending from the same median corner region 34 in axial directions opposite their respective corner cutting edges 46. As seen in the side corner view of Fig. 3, the two partially tapered corner relief surfaces 52 can overlap in the axial direction of the cutting insert 20.
    [0045] It should be appreciated that with respect to the Eb insert contour line, each partially conical corner relief surface 52, also known as a 'inverted' relief surface, generally extends inward (ie, in a direction of the insert geometric axisAl) from its associated median corner region 34 towards its respective corner cutting edge 46, so that each corner cutting edge 46 is beneficially supported and advantageously robust.
    [0046] In some embodiments of the present invention, as shown in Fig. 3, each corner surface 28 can include two secondary raised planks 54 extending from the same median corner region 34 in axial directions opposite to their respective secondary cutting edges 48. As seen in the side corner view of Fig. 3, the two secondary flat relief surfaces 54 may not overlap in the axial direction of the cutting insert 20.
    [0047] Also, in some embodiments of the present invention, each secondary relief surface 54 may be perpendicular to the median plane M.
    [0048] In addition, in some embodiments of the present invention, each secondary embossed surface 54 can be spaced from its adjacent side surface 26 by a non-flat joining surface 68.
    [0049] According to the present invention, as shown in Fig. 2a, each corner surface 28 has a corner bisecting plane Pc containing the insert geometric axisAl.
    [0050] In some embodiments of the present invention, each corner cutting edge 46 may intersect its associated corner bisector plane Pc, and its first and second end points E1, E2 may be located on opposite sides of the bisector plane of Pc corner. However, as seen in the side corner view of Fig. 3, the corner bisector plane Pc may not pass through the highest point of the corner cutting edge 46. Also, as seen in the enlarged end view of Fig. 2b , the corner bisector plane Pc may not bisect the corner cut edge 46 (ie, it does not need to pass halfway between its first and second end points El, E2.)
    [0051] Also, in some embodiments of the present invention, as shown in Fig. 3, each median corner region 34 may show specular symmetry around its associated corner bisector plane Pc.
    [0052] Furthermore for embodiments of the present invention having flat lateral median regions 32 perpendicular to the median plane M, each lateral median region 32 can form a first bisector angle ocl with the corner bisector plane Pc of an adjacent corner surface 28 , having a value of 30 °.
    [0053] Furthermore, for embodiments of the present invention having plane secondary raised surfaces 54 perpendicular to the median plane M, each secondary raised surface 54 can form a second bisector angle oc2 with its associated corner bisector plane Pc, having a between 60 ° and as shown in Fig. 6, a second imaginary straight line L2 extending perpendicular to the median plane M and intersecting any of the main cutting edges 44 at any point along its length, can pass through the median plane M within the insert contour line Lb.
    [0054] In some embodiments of the present invention, as shown in Fig. 4, each side surface 26 may include two main embossed surfaces 56 extending from the same median side region 32 to the respective main cutting edges 44 .
    [0055] In addition, in some embodiments of the present invention, each main cutting edge 44 can be substantially straight along its entire length, and each main embossed surface 56 can be substantially flat.
    [0056] It should be appreciated that with respect to the insert contour line Lb, each main embossed surface 56, also known as an 'inverted' embossed surface, generally extends inward (ie, in a direction of the geometric axis insert) from its associated median lateral region 32 towards its respective main cutting edge 44, so that each main cutting edge 44 is beneficially supported and advantageously robust.
    [0057] As shown in Figs. 7 to 10, the present invention also relates to a cutting tool 58 rotatable around a geometric axis of tool A3, in a direction of rotation Z, having a cutting body 60 and at least one of the reversible orientable cutting inserts mentioned above 20. Each cutting insert 20 is removably trapped in an insert receiving cavity 62 of the cutting body 60.
    [0058] In some embodiments of the present invention, each cutting insert 20 can be removably secured in the insert receiving cavity 62 by means of a clamping screw 64 that passes through its through hole 38, and threadedly engages a hole for screw (not shown) on a seating surface (not shown) of the insert receiving cavity 62.
    [0059] As shown in Fig. 10, each cutting insert 20 can be configured within the cutting tool 58 so that during rotation of the cutting tool 58 around its geometric tool axis A3, the corner cutting edge operative 46 inscribes a first arc-shaped contour line Cl on a radial plane Pr containing the tool geometry axis A3, with the first contour line Cl having a constant radius of curvature R subtending a corner cutting angle δ of 90 °.
    [0060] Also, as shown in Fig. 10, each cutting insert 20 can be configured inside the cutting tool 58 so that during rotation of the cutting tool 58 around its geometric tool axis A3, the cutting edges main and secondary operatives 44, 48 inscribe the second and third straight contour lines C2, C3, respectively, in the radial plane Pr, with the second contour line C2 substantially parallel to the tool axis A3 and the third contour line C3 substantially perpendicular to the A3 tool axis.
    [0061] Throughout the description, it should be appreciated that the parallelism and perpendicularity of the second and third contour lines C2, C3, respectively, with respect to the tool geometry axis A3 have an accuracy tolerance of 0.5 °.
    [0062] In some embodiments of the present invention, the rotary cutting tool 58 can be used for milling operations.
    [0063] It should be appreciated that during a milling operation, the operating corner cutting edge 46 cuts a corner in a workpiece (not shown) having a constant radius of curvature R subtending a corner cutting angle δ of 90 °, advantageously resulting in reduced stress concentrations in the corner, and thus minimizing your risk of fracture.
    [0064] It should also be appreciated that during a milling operation, the operative secondary cutting edge 48, which can also be referred to as a cleaner, is parallel to the workpiece surface, promoting a smooth and uniform surface finish.
    [0065] It should also be appreciated that during a milling operation, the main 'inverted' relief surfaces 56 beneficially provide the non-operating main trailing cutting edges 44 of each reversible cutting insert 20 with greater clearance from the workpiece. thus enabling it to be advantageously placed on cutting tools of relatively less diameter 58.
    [0066] In some embodiments of the present invention, as can be readily understood from Fig. 10, each cutting insert 20 can be configured within the cutting tool 58, so that the main operating cutting edges, corner and secondary 44, 46, 48 perform a square boss, or 90 °, milling operation on the workpiece.
    [0067] It should be appreciated that during a milling operation with square boss, or 90 °, the height of the machined boss is not limited by the cutting insert 20.
    [0068] In some embodiments of the present invention, as shown in Figs. 8 and 9, each cutting insert 20 can be configured within the cutting tool 58, so that the operating main cutting edge 44 has a positive axial tilt angle β, and the operating secondary cutting edge 48 has an angle of positive radial slope 0.
    [0069] It should be appreciated that by providing the main and secondary operating cutting edges 44, 48 with positive axial and radial inclination angles β, 0, respectively, lower cutting forces are generated, the machine spindle requires less operating power , and the workpiece undergoes a smoother cutting action. The cut chips produced are also advantageously evacuated out from the operating cutting edges.
    [0070] In some embodiments of the present invention, each side edge 40 may include an auxiliary cutting edge 66 extending from its associated main cutting edge 44 to an adjacent secondary cutting edge 48 belonging to a cutting edge. adjacent corner 42.
    [0071] Each cutting insert 20 can be configured within the cutting tool 58, so that the auxiliary cutting edge 66 adjacent to the operative secondary cutting edge 48 is operative during ramp forming operations.
    [0072] Each cutting insert 20 can also be configured within the cutting tool 58, so that the auxiliary cutting edge 66 extending from the operative main cutting edge 44 is operative during boss milling operations, increasing thus the cutting depth of the insert.
    [0073] As seen in the side views of Figs. 3 and 4, the auxiliary cutting edge 66 may be angled to a lesser extent than its associated main cutting edge 44. In some embodiments, the auxiliary cutting edge 66 may be parallel to the median plane M.
    [0074] Also, in some embodiments of the present invention, each auxiliary cutting edge 66 can be substantially coplanar with its associated support surface 30.
    [0075] In addition, in some embodiments of the present invention, each end surface 22 may include an inclined auxiliary groove (not shown) extending longitudinally adjacent to each auxiliary cutting edge 66 to promote efficient chip evacuation during ramp formation operations.
    [0076] Although the present invention has been described to a certain degree, it should be understood that various changes and modifications could be made without departing from the spirit or scope of the invention claimed below.
