The direct laser-assisted machining (DLAM) technique is introduced to improve the CFRP machining process. The DLAM technique applies focused laser at the tool edge through a sapphire tool. A fibre laser with 4.3 W power was used to have the desired t

This paper presents the prediction of micro-milling forces using cutting force coefficients evaluated from the finite element (FE) simulations. First an FE model of orthogonal micro-cutting with a round cutting edge is developed for Brass 260. The si
