Abstract: A cutting member comprising a cutting edge (S1,S2,Si) defining a cutting envelope and configured for removing material from a workpiece leaving therein a corner of angle α. The cutting edge comprises a first cutting segment (S1) and a second cutting segment (S2) spaced from the first cutting segment (S2). Respective first and second imaginary tangents (T1,T2) of the first and second cutting segments (S1,S2) intersect one another at point O located outside the cutting envelope, forming an angle corresponding to angle α, thereby defining a cutting frame at least a portion of which extends beyond the cutting envelope. The cutting edge further comprises an adjoining cutting segment (Si), extending between and bridging the first cutting segment (S1) and the second cutting segment (S2), and at least partially contained within the cutting frame. The cutting member further comprises at least one auxiliary cutting element (AT1,AT2) comprising an auxiliary cutting edge (CE′,CE″) extending generally along one of the imaginary tangents (T1,T2) and beyond the cutting envelope. The auxiliary cutting edge (CE′,CE″) does not intersect the other of the imaginary tangents (CE″,CE′) and/or a bisector (B) of the angle α.

Abstract: A method for designing a cutting edge of a cutting element configured for removing material from a workpiece to leave therein a desired end profile (B22,B24,B26). The method comprises the steps of modeling a desired end profile (B22,B24,B26) of the workpiece, the profile having a longitudinal axis and being defined by a bottom surface (B12), a side surface (B16) and an adjustment surface (B14) extending therebetween; defining a lead profile plane (RPL) and an trail profile plane (RPT) spaced therefrom, each of the planes being oriented perpendicular to the longitudinal axis; determining a profile contour defined by the intersection line between the end profile (B22,B24,B26) and the lead profile plane (RPL). The contour profile includes a bottom contour, an adjoining contour and a side contour defined as the intersection lines between the lead profile plane (RPL) and the bottom surface (B12), the adjustment surface (B14) and the side surface (B16) respectively; designing a rake surface and a relief surface, the intersection line between which defines a cutting edge lying in the adjoining surface (B14) and spanning between the lead profile plane (RPL) and the trail profile plane (RPT). The cutting edge is designed such that in any reference plane (RP; FIG. 6A) oriented perpendicularly to the cutting edge, the intersection between each of the rake surface and the relief surface with the reference plane (RP) defines a respective rake line (RK; FIG. 7) and relief line (RF; FIG. 7), the angle (θB) between the lines RK,RF) being equal to or smaller than a similar angle (θB) taken along each of a plurality of similar reference planes (RP) disposed between the reference plane (RPn) and the lead profile plane (RPL).

Abstract: A cutting member comprising a cutting edge (S1, S2, Si,) defining a cutting envelope and configured for removing material from a workpiece leaving therein a corner of angle α. The cutting edge comprises a first cutting segment (Si) and a second cutting segment (S2) spaced from the first cutting segment (S2). Respective first and second imaginary tangents (T1, T2) of the first and second cutting segments (S1, S2) intersect one another at point O located outside the cutting envelope, forming an angle corresponding to angle α, thereby defining a cutting frame at least a portion of which extends beyond the cutting envelope. The cutting edge further comprises an adjoining cutting segment (Si), extending between and bridging the first cutting segment (S1) and the second cutting segment (S2), and at least partially contained within the cutting frame. The cutting member further comprises at least one auxiliary cutting element (AT1, AT2) comprising an auxiliary cutting edge (CE′, CE″) extending generally along one of the imaginary tangents (T1 , T2) and beyond the cutting envelope. The auxiliary cutting edge (CE′, CE″) does not intersect the other of the imaginary tangents (CE″, CE′) and/or a bisector (B) of the angle α.
Abstract translation: 切割构件包括限定切割外壳的切削刃（S1，S2，Si），并且构造成用于从其中留下角度为α的工件移除材料。 切割刃包括与第一切割段（S2）间隔开的第一切割段（Si）和第二切割段（S2）。 第一和第二切割段（S1，S2）的相应的第一和第二假想切线（T1，T2）在位于切割外壳外部的点O彼此相交，形成对应于角度α的角度，从而至少限定切割框架 其一部分延伸超过切割外壳。 刀刃还包括邻接的切割段（Si），其在第一切割段（S1）和第二切割段（S2）之间延伸并桥接，并且至少部分地包含在切割框架内。 所述切割构件还包括至少一个辅助切割元件（AT1，AT2），所述辅助切割元件（AT1，AT2）包括大致沿着所述假想切线（T1，T2）之一延伸并且超过所述切割外壳延伸的辅助切割刃（CE'，CE“）。 辅助切削刃（CE'，CE“）不与角度α的假想切线（CE”，CE“）和/或平分线（B）中的另一个相交。
