Outstanding mechanical characteristics make metal matrix composites (MMCs) applicable to many industrial applications. However, the very hard reinforcements that provide such remarkable features for MMCs also cause challenges during the machining process. This paper tries to address these challenges through development of a novel analytical model for prediction of cutting force during machining these composites. The force model is based on calculation of power consumption in different parts of the cutting system. The model considers the plastic deformations, different types of friction at various interfaces and debonding and fracture of reinforcements. The cutting force values predicted by the model are compared with experimental values for various MMCs at different cutting conditions. The close agreement between the results verifies the ability of the model to provide accurate estimation of the cutting force during machining MMCs.

“…Hence, in these cases the adhesive force between metal matrix and ceramic particles is lower than the cohesive forces in copper and in aluminum oxide. On the other hand, in Ref 15,16 it was observed that the particles in composites containing a high volume fraction of reinforcement are the weakest part of the composite. It confirms that the production technology and the metal-to-ceramic ratio play an essential role in the metal matrix composite failure mechanism.…”

This study investigated the influence of the particle size on the adhesion force between ceramic particles and metal matrix in ceramic-reinforced metal matrix composites. The Cu-Al 2 O 3 composites with 5 vol.% of ceramic phase were prepared by a powder metallurgy process. Alumina oxide powder as an electrocorundum (Al 2 O 3 ) powder with different particle sizes, i.e., fine powder <3 lm and coarse powder of 180 lm was used as a reinforcement. Microstructural investigations included analyses using scanning electron microscopy with an integrated EDS microanalysis system and transmission microscopy. In order to measure the adhesion force (interface strength), we prepared the microwires made of the investigated materials and carried out the experiments with the use of the self-made tensile tester. We have observed that the interface strength is higher for the sample with coarse particles and is equal to 74 ± 4 MPa and it is equal to 68 ± 3 MPa for the sample with fine ceramic particles.
