摘要： In a semi-finishing cutter, rectangular tips and square tips are disposed in a staggered pattern in an axial direction in second to fourth step portions, so a single cutting edge is formed by a pair of one of the rectangular tips and one of the square tips. It is therefore possible to effectively reduce a frequency of contact with a blade root. A cutting speed of the semi-finishing cutter may be increased and a cutting feed may be made faster, so work in a semi-finishing process may be performed efficiently. The rectangular tips and the square tips have simple shapes, so known commercially available throwaway tips may be used. Accordingly, it is possible to provide the semi-finishing cutter in an easy-to-use form without increasing the cost.
摘要翻译：在半精加工刀具中，矩形尖端和方形尖端在第二至第四台阶部沿轴向布置成交错图案，因此单个切割刃由一对矩形尖端和正方形之一形成提示。因此，可以有效地降低与叶片根部的接触频率。可以提高半精加工刀具的切削速度，并且可以使切削进给更快，因此可以有效地进行半精加工工序。矩形尖端和方形尖端具有简单的形状，因此可以使用公知的市售的一次性顶端。因此，可以在不增加成本的情况下以易于使用的形式提供半精加工刀具。

摘要： In a rough cutting cutter, square tips and rectangular tips are disposed in a staggered pattern in an axial direction in second to fourth step portions, so a cutting edge is formed by a pair of one of the square tips and one of the rectangular tips. It is therefore possible to effectively reduce a frequency of contact with a blade root. Furthermore, in the second to a fifth step portions, ARs (rake angles in the axial direction) and RRs (rake angles in a radial direction) of the square tips and the rectangular tips gradually increase in order from a tip end to a back end of a tool body. It is therefore possible to suppress chatter vibration during machining and is possible to reduce roughness of a cut surface of a work material.

摘要： A throw-away rotating tool includes at least two grooved portions 13b, 13c formed on each of erected portions 13 and at least two protrusions 26, 27 for fitting into and removal from respective grooved portions 13b, 13c and projected from a projecting coupling portion 23, and the grooved portions 13b, 13c are formed asymmetrically about an axis O and the protrusions 26, 27 are formed asymmetrically about the axis. Thus, the direction in which the projecting coupling portion 23 can be coupled to the erected portions 13 is uniquely determined. Consequently, variations in lip height and run-out can be minimized. As a result, occurrence of a bend and an increase in machined hole diameter during drilling can be prevented, thereby making it possible to minimize variations in machining accuracy and tool life.

摘要： A throw-away rotating tool includes plural protrusions formed in a part of an outer peripheral wall of a projecting coupling portion. Since the twist angle and a twist direction of the protrusions are set in such a way that with relative rotation when coupling the projecting coupling portion and erected portions together, due to the reaction force received by the protrusions from inner peripheral walls, the projecting coupling portion is pulled to the rear and side of the erected portions and the projecting coupling portion is stably held between the erected portions. Since the number of portions that require stringent dimension control and high machining accuracy can be reduced, productivity can be improved.
摘要翻译：抛弃旋转工具包括形成在突出联接部分的外周壁的一部分中的多个突起。由于突起的扭转角度和扭转方向被设定为使得当将突出联接部和竖立部分联接在一起时由于由内周壁突出部接收的反作用力而相对旋转，所以突出联接部被拉到竖立部分的后侧和侧面，并且突出联接部分被稳定地保持在竖立部分之间。由于可以减少需要严格尺寸控制和高加工精度的部件的数量，所以可以提高生产率。
