摘要： A radius endmill has a peripheral cutting edge, a bottom cutting edge, and a rounded corner cutting edges whose ridge line is defined by a circular arc having a given radius as measured in a side view of the endmill that is parallel to the axis. The rounded corner cutting edge is located in a corner portion of the endmill in which the outer peripheral and the axial end intersect each other such that the peripheral cutting edge and the bottom cutting edge are connected to each other through the rounded corner cutting edge. The bottom cutting edge has a radially inner end lying at the axis, and a radially outer end at which the bottom cutting edge is connected to the rounded corner cutting edge. The bottom cutting edge is curved such that its ridge line is defined by a circular arc as seen in a plan view of the endmill that is perpendicular to the axis.
摘要翻译：半径终端铣刀具有外围切割边缘，底部切割边缘和圆角切割边缘，其棱线由具有给定半径的圆弧限定，其在端铣刀的平行于轴线的侧视图中测量。圆角切削刃位于端铣刀的角部，外圆周和轴向端部彼此相交，使得周边切削刃和底切削刃通过圆角切削刃相互连接。底部切削刃具有位于轴线处的径向内端，以及底部切削刃连接到圆角切削刃的径向外端。底部切割边缘是弯曲的，使得其脊线由垂直于轴线的端铣刀的平面图中看到的圆弧限定。
