The two basic precision requirements for ultra precision diamond cutting tool are the precision of outline and edge radius.
超精密金刚石刀具的两个基本精度要求是刀刃轮廓精度和刃口半径。
By researching relation between cutting edge radius and force to cut synthetic fiber it develops a technique for measuring the sharpness of tools.
通过研究刀具刃口半径与刀具切断纤维的力之间的关系，提出了一种检测加工刀具锋利性能的方法。
The result shows that the cutter blade edge radius, edge angle, the linear abrasion and the edge notch depth are main factors affecting its sharpness.
分析结果表明， 纤维切割过程中，切断刀锋利性能的变化主要与切断刀的初始刃口半径、刃口角度、刃口的磨损量以及刃口上缺口的深度有关。
