微铣削通常用于工业精密部件的生产。刀具过早磨损通常是造成硬质合金立铣刀刀具寿命短的原因。改善刀具磨损性能的一种方法是定义切削刃准备。本文介绍并讨论了微铣刀浸入式翻滚过程中切削刃几何形状形成的实验研究。结果表明，可以制备出直径D = 1 mm的立铣刀，刃口半径4.0 μm≤rβ≤31.2 μm。对微铣削作业中切削刃几何形状与刀具磨损行为之间相关性的研究表明，由于适当的切削刃制备，减少了侧面和陨石坑的磨损。
Micro milling is commonly used industrially for the production of precision components. Premature tool wear is usually the reason for a short tool life of cemented carbide end mills. An approach to improve the tool wear behavior is the defined cutting edge preparation. In this contribution, experimental investigations on the formation of cutting edge geometry during immersed tumbling of micro milling tools are presented and discussed. It could be shown that it is possible to prepare end mills with a diameter D = 1 mm and to generate edge radii of 4.0 μm ≤ rβ ≤ 31.2 μm. Investigations about the correlations between the cutting edge geometry and the tool wear behavior in micro milling operations showed decreased flank and crater wear as a result of an appropriate cutting edge preparation.
