摘要： A cutting insert for a multifunctional endmill is capable of using three corners. The cutting insert includes a top surface and a bottom surface having an outer shape of a substantially polygonal shape and four side surfaces extending between the top surface and the bottom surface, a first side surface has a positive flank angle, a second side surface has a positive flank angle, a third side surface has the positive flank angle, the first side surface includes a first and a second component surfaces connected with each other so that the first side surface protrudes outward from a peripheral surface of the cutting insert, and a connection portion between a first and a second component surface extends between the top surface and the bottom surface.

摘要： A cutting insert is arranged in a tangential direction on an outer peripheral portion of a tool body, the cutting insert having a reduced area in a top view thereof. The cutting insert has an upper face, a lower face and at least five side faces extending between the upper and lower faces. The upper face of the cutting insert has at least five intersection portions intersecting with the at least five side faces. The at least five intersection portions include first and second intersection portions and third and fourth intersection portions shorter than the first and second intersection portions, respectively. A cutting edge is formed at each of the first and second intersection portions. A rake face is formed on cutting side faces corresponding to the first and second intersection portions, respectively, while a cutting edge flank is formed on the upper face.

摘要： A fully indexable square cutting insert has four side surfaces connecting to two end surfaces. At the intersection of each side surface with an end surface is a primary cutting edge which extends from an insert corner and along a first side surface, in a downward direction towards a median plane. A wiper extends from the same insert corner and along an adjacent side surface, in an upward direction away from the median plane, to rise above an abutment surface of an associated end surface. The geometry of the cutting insert and of the insert pocket in which the insert is seated are such that the primary cutting edge has a positive axial angle (helix), while the insert has an overall negative axial angle for providing axial clearance and an overall negative radial angle for providing radial clearance.
摘要翻译：完全可转位的方形切削刀片具有连接到两个端面的四个侧表面。在每个侧表面与端表面的交叉点处是主要切削刃，其从插入角部并且沿着第一侧表面朝向中间平面向下的方向延伸。擦拭器从相同的插入角延伸并且沿着相邻的侧表面沿远离中间平面的向上的方向延伸，以在相关联的端面的邻接表面上方升高。切削刀片和插入件所在的刀片槽的几何形状使得主切削刃具有正的轴向角（螺旋），而刀片具有用于提供轴向间隙的总体负轴向角度，并且总体为负用于提供径向间隙的径向角度。
