摘要： An improved cutting insert with chip control features and a method for manufacturing the same. An insert body having wall regions, sides and top and bottom walls is adapted for mounting in a pocket in a holder. The insert body has cutting edges and a diagonal notch in the top and bottom sides. A land region extends rearwardly from the end wall region toward the respective top or bottom wall and defines a surface region of a predetermined width. A descending wall initiates in a portion of the land and terminates in a planar floor region having a forward, a rearward and opposed side edges. A back ramp extends upwardly from the planar floor rearward edge and terminates at the respective top or bottom wall. The end wall region can include at least one flat land region adjacent the land region. The flat land region defines a selectively removable portion of the end wall region and after any selective removal thereof represents no more than approximately one-third of the total width of the end wall region.

摘要翻译： 一种具有芯片控制特征的改进的切削刀片及其制造方法。 具有壁区域，侧面和顶壁和底壁的插入体适于安装在保持器中的口袋中。 插入体在顶部和底部具有切割边缘和对角线凹口。 陆地区域从端壁区域朝向相应的顶壁或底壁向后延伸，并且限定了预定宽度的表面区域。 一个下降的壁在一部分地面上开始并且终止于具有前向，后向和相对的侧边缘的平坦的地板区域。 后斜面从平坦的地板后边缘向上延伸并且终止于相应的顶壁或底壁。 端壁区域可以包括与陆地区域相邻的至少一个平坦的陆地区域。 平坦的陆地区域限定了端壁区域的可选择性地移除的部分，并且在其任何选择性移除之后不超过端壁区域的总宽度的大约三分之一。

摘要： An improved cutting insert with chip control features and a method for manufacturing the same. An insert body having wall regions, sides and top and bottom walls is adapted for mounting in a pocket in a holder. The insert body has cutting edges and a diagonal notch in the top and bottom sides. A land region extends rearwardly from the end wall region toward the respective top or bottom wall and defines a surface region of a predetermined width. A descending wall initiates in a portion of the land and terminates in a planar floor region having a forward, a rearward and opposed side edges. A back ramp extends upwardly from the planar floor rearward edge and terminates at the respective top or bottom wall. The end wall region can include at least one flat land region adjacent the land region. The flat land region defines a selectively removable portion of the end wall region and after any selective removal thereof represents no more than approximately one-third of the total width of the end wall region.
