摘要： An indexable insert (10) is located on a toolholder (40) with reference to bearing surfaces (80,82) on the insert and the toolholder which are proximate to the active cutting edge. These bearing surfaces (80,82) are internal to the peripheral (side) flanks (18) of the insert. Location of the insert in the toolholder is substantially independent of the relation between the toolholder pocket sidewalls and the peripheral flanks (18) of the insert, thereby eliminating sources of error from insert manufacture and pocket manufacture. The insert (10) and toolholder (40) have locating units (30,32) disposed thereon adapted to matingly engage each other when the insert (10) is placed in the toolholder (40). At least one of the locator elements (30,32) has a bearing surface (80,82) or surfaces that extends through 360° and resulting in less movement of the insert (10) during use.
摘要翻译：参考插入件上的支承表面（80,82）和靠近有效切削刃的刀夹具，可转位刀片（10）位于刀夹（40）上。这些支承表面（80,82）在插入件的外围（侧面）侧面（18）的内部。插入件在刀夹中的位置基本上与刀夹槽口侧壁和插入件的周边侧面（18）之间的关系无关，由此消除了插入件制造和口袋制造中的误差源。刀片（10）和刀夹（40）具有设置在其上的定位单元（30,32），适于在刀片（10）被放置在刀夹（40）中时彼此配合地接合。至少一个定位元件（30,32）具有支承表面（80,82）或多个延伸360°的表面，并且在使用期间导致插入物（10）的较少移动。
