One of the effective strategies to improve dry machining processes is the implementation of micro-textured cutting tools. Micro-textures decrease the chip-tool contact length and thus reduce friction and heat which lead to better surface quality and longer tool life. However, micro-cutting of the bottom side of the chip, known as derivative cutting, is an issue when using textured tools. Derivative cutting increases the cutting forces, heat, and ultimately tool wear. This paper investigates the effect of micro-texture design parameters on the occurrence of derivative cutting and offers design recommendations when preparing micro-grooves to eliminate/reduce the severity of this phenomenon.

改进干式加工工艺的有效策略之一是采用微纹理刀具。微纹理减少了切屑与刀具的接触长度，从而减少了摩擦和热量，从而提高了表面质量并延长了刀具寿命。然而，芯片底部的微切削（称为衍生切削）是使用纹理工具时的一个问题。微分切削会增加切削力、热量，并最终增加刀具磨损。本文研究了微纹理设计参数对衍生切削发生的影响，并在制备微凹槽时提供设计建议，以消除/减少这种现象的严重性。
