    [009] In the following description, various aspects of the present invention will be described. For purposes of explanation, specific configurations and details are presented in order to provide a complete understanding of the present invention. However, it will also be apparent to one skilled in the art that the present invention can be practiced without the specific details presented herein. In addition, well-known features can be omitted or simplified in order not to obscure the present invention.
    [0010] Reference is now made to Figures 1-4, representing a cutting tool 150 according to an embodiment of the present invention. The cutting tool 150 has a tool body 152 with a geometric axis of rotation R. The tool body 152 has a plurality of insert cavities 154 formed on the periphery thereof, the insert cavities 154 are arranged symmetrically about the axis rotation geometric R. A plurality of cutting inserts 100 according to the present invention are retained in the insert cavities 154. Each cutting insert 100 is fixed to the respective insert cavity 154 with a gripping member 164 that passes through a gripping hole 130 in the cutting insert 100 and through a fixing hole 162 in the insert cavity 154.
    [0011] With additional reference to Figures 5-7, each insert cavity 154 has a cavity supporting surface 156 and a plurality of gripping walls 158 that extends transversely to the cavity supporting surface 156. The fixing hole 162 extends transversely to the cavity supporting surface 156 and opens onto it.
    [0012] Reference is additionally made to Figures 8-14, representing various views of the cutting insert 100 according to an embodiment of the present invention. The cutting insert 100 is a double-sided indexable cutting insert 100 having a central insert geometric axis A, and a medium insert plane P, which extends perpendicular to the insert geometric axis A. The cutting insert 100 comprises two end surfaces 102 and a peripheral surface 104 that extends between them. The intersection of peripheral surface 104 with each of the two end surfaces 102 forms a pair of peripheral edges 103. End surfaces 102 are located on opposite sides of the median plane P and rotationally symmetrical to each other around bisector B that extends along the middle plane P. Each end surface 102 has a trine shape, with three primary vertices 106 and three secondary vertices 108, arranged alternately. The gripping hole 130 extends along the insert geometric axis A, and opens at least to one of the end surfaces 102. In the embodiment shown in the Figures, the gripping hole 130 is a through hole, which opens for both the end surfaces.
    [0013] The peripheral edges 103 of the cutting insert 100 define six cutting portions 110, each formed between the peripheral surface 104 and one of the end surfaces 102 at one of its primary vertices 106. Each cutting portion 110 comprises a first cutting edge 112 and a second cutting edge 114 extending transversely to the first cutting edge 112. A pointed cutting edge 116 (i.e., a corner cutting edge), corresponding to the primary vertex 106, extends between the first and second cutting edges 112, 114, connecting the two edges. A skewed cutting edge 118 extends between the second cutting edge 114 of each cutting portion 110 and the first cutting edge 112 of an adjacent cutting portion 110.
    [0014] The peripheral surface 104 has a plurality of gap surfaces 120, each extending from one of the second cutting edges 114 in the direction of the middle plane P. The gap surfaces 120 typically end before the middle plane P. Thus, each second cutting edge 114 is indented inwardly from peripheral surface 104. Peripheral surface 104 also has a plurality of relief surfaces 134, each extending along one of the cutting portions 110. Relief surface 134 extends along the respective first cutting edge 112 and the pointed cutting edge 116 towards the middle plane P.
    [0015] The peripheral surface 104 has six lateral flanks 136 formed therein. Each side flank 136 extends between a pair of primary vertices 106 located on opposite sides of the median plane P, and an adjacent pair of secondary vertices 108 located on opposite sides of the median plane P. Side flanks 136 are flat and parallel to the geometric axis of insert A. At each primary vertex 106, each pair of adjacent lateral flanks 136 forms a first acute angle α between them. This is indicated, for example, in the top view of Figure 8. In some embodiments, the first acute angle a is in the range of 82 ° to 86 °, and in a particular mode, the first acute angle α is an angle of 84 ° .
    [0016] Each of the first cutting edges 112 has a main portion 122 that extends from the respective cutting edge edge 116 towards the middle plane P. In the embodiment shown in the attached figures, the main portion 122 extends substantially perpendicular to the second cutting edge 114 of the same cutting portion 110, allowing metal to be cut from a substantially perpendicular corner in a workpiece. Typically, main portion 122 may be at an angle of between 89 ° to 91 ° with the second cutting edge 114 of the same cutting portion 110, for example, due to manufacturing tolerances. In the embodiment shown in the Figures, the main portion 122 of the first cutting edge 112 is larger than the second cutting edge 114. In some embodiments, the main portion 122 of the first cutting edge 112 can be constructed as a linear cutting edge. A curved portion 124 extends from the main portion 122, curving away from the median plane P. The skewed cutting edge 118 extends from the second cutting edge 114 of each cutting portion 110 towards the curved portion 124 another cutting portion 110.
    [0017] Figure 11, represents a side view of the cutting insert 100 taken along the middle plane P and along a bisector B passing through one of the secondary vertices 108 and one of the primary vertices 106 (see Figure 8), and seen from the secondary vertex 108. In this view, the main portion 122 of each of the first cutting edges 112 forms a second acute angle β with the median plane P. In some embodiments, the second acute angle β is in the range of 11 ° to 14 °, and in a particular mode, the second acute angle β is an angle of 13 °. As additionally shown in this side view, the skewed cutting edge 118 forms a third acute angle y with the median plane P. The third acute angle Y is similar to the second acute angle β. In some embodiments, the third acute angle y is in the range of 11 ° to 14 °, and in a particular embodiment, the third acute angle y is an angle of 13 °. In addition, Figure 12 represents another side view of the cutting insert 100 taken along the median plane P and along a bisector B, seen from the primary vertex 106.
    [0018] The skewed cutting edge 118 is operative during skew operations on a metal workpiece (eg skew milling, helical interpolation, circular skew, etc.), when the cutting tool 150 progresses along the axis of rotation R (that is, in the longitudinal direction, possibly in combination with other directions). The side flanks 136 thus place the respective skewed cutting edge 118 at a first acute angle a with respect to the main portion 122 of the respective first cutting edge 112. In this way, when the cutting insert 100 is engaged in an operation the skewed cutting edge 118 has sufficient clearance to cut metal chips from the workpiece surface. This allows the cutting insert 100 to perform skew operations on the metal workpiece involving the skewed cutting edge 118, which would not be possible if angle α was a non-acute angle. It would be appreciated that in non-skewed milling operations (eg face milling, boss milling, end milling, profile milling, turning milling, etc.), the skewed cutting edge 118 is non-operative, kept away from the part of work.
    [0019] Each end surface 102 has an insert support surface 126 for support against the cavity support surface 156 of insert cavity 154. Each insert support surface 126 has a respective AP support plane. The AP support planes of the insert support surfaces 126 are parallel to the middle plane P and equidistant from it. Each support plane AP is located at a first distance Dl from the median plane P (see Figure 11). As shown in particular in Figures 11 and 14, each support plane AP is between the middle plane P and the curved portions 124 of the respective first cutting edges 112, that is, the first cutting edges 112 which are located on the same side of the medium plan P as the AP support plan. In the modality shown, the totality of each peripheral edge 103 is more distant from the middle plane P than the support plane AP on the respective associated side of the middle plane P. Thus, it would be recognized that the extension of the first cutting edge 112 faces away from the P medium plan and the respective AP support plan, and does not intersect with the AP support plan. In other words, each of the curved portions 124 (and thus the entire first cutting edge 112) lies between an adjacent support plane AP and an adjacent primary vertex 106, in a direction parallel to the central insert geometric axis A.
    [0020] At points furthest from the median plane P, the primary vertices 106 on each end surface 102 define a tip plane TP which is parallel to an adjacent support plane associated with AP and spaced from it by a second distance D2. At points closer to the median plane P, the secondary vertices 108 on each end surface 102 define a corner plane CP which is parallel to an adjacent support plane associated with AP and spaced by a third distance D3, with the third distance D3 being smaller than the second distance D2 (that is, D3 <D2). The TP tip plane and the CP corner plane are both on the same side of its associated AP support plane. A ratio between the third distance D3 and the second distance D2 (that is, D3: D2) is between 0.04 and 0.1. In a particularly preferred embodiment, the D3: D2 ratio is about 0.06.
    [0021] Figure 13 represents a cross-sectional view of the cutting insert 100 taken along the cutting line XIII-XIII seen in Figure 8, passing through one of the primary vertices 106 and the opposite secondary vertex 108. Each surface of end 102 has three spaced support recesses 128, each formed adjacent to one of the secondary vertices 108, between the secondary vertex 108 and the insert geometric axis A (i.e., arranged symmetrically about the insert geometric axis A).
    [0022] Each cutting portion 110 of the cutting insert 100 includes an inclined surface 132 that extends along the respective first, second cutting edges and tip and skewed cutting edges 112,114,116, 118 and slanting obliquely towards the middle plane P. The inclined surface 132 is the surface on which the chips removed from the workpiece slide. In particular, the inclined surface 132 extends along the main portion 122 and the curved portion 124 of the first cutting edge 112, as well as along the skewed cutting edge 118 of the same cutting portion 110. Each supporting recess 128 is located adjacent to a respective curved portion 124, allowing metal chips removed by the curved portion 124 to flow over it, thus enabling better chip flow from the cutting portion 110.
    [0023] The cutting insert 100 is retained in the respective insert cavity 154, with the insert supporting surface 126 supporting (i.e., received by) the gripping walls 158 of the insert cavity 154. The gripping walls 158 can be flat surfaces forming an acute angle with the plane of the cavity supporting surface 156. This would ensure contact with the lateral flanks 136 of the cutting insert 100 at a predetermined desired location.
    [0024] In order to ensure firm support between the insert support surface 126 and the cavity support surface 156, each cavity support surface 156 has three spaced cavity recesses 160 formed therein, spaced from the fixing hole 162. As seen in Figure 6, cavity recesses 160 are also spaced from an outer peripheral surface 153 of tool body 152. When cutting insert 100 is placed in insert cavity 154, each recess in cavity 160 overlaps, at least partially, with one of the supporting recesses 128 of the cutting insert 100. This recess overlap positioning with recess forms three voids, resulting in three separate support regions between the insert support surface 126 and the support surface of cavity 156, ensuring firm support between them.
    [0025] As shown in Figures 1, 3 and 5, when the cutting insert 100 is mounted in the insert cavity 154, one of the cutting portions 110 (i.e., the operative cutting portion 110) extends outside the circumference tool body 152 and is thus ready for use in a metal cutting operation. A plurality of refrigerant channels are formed through the tool body 152, each refrigerant channel opening at a refrigerant outlet 166 towards one of the insert cavities 154. In this way, the refrigerant fluid supplied through the refrigerant channels can be sprayed towards the operative cutting portion 110.
    [0026] Although the present invention has been described with reference to one or more specific modalities, the description is intended to be illustrative as a whole and should not be construed as limiting the invention to the modalities shown. It is recognized that various modifications may occur to those skilled in the art which, although not specifically shown here, are nevertheless within the scope of the invention.
