Evaluation of tool wear when milling SiCp/Al Composites S.T.
Milling is another important machining method for SiCp/Al composites, but there are few works related to the influence of milling characteristics of SiCp/Al composites, especially for the high volume fraction SiCp/Al composites.
The experimental material is CY1110 SiCp/Al composites.

All metallic sheet surfaces were pretreated with an AC-130 sol-gel post-treatment after corundum-blasting with 105 μm particles and then added to the laminate stacking within one hour, as described by Stefaniak et al. [2].
Xue et al. [9] is used for the present investigations.
The advantages of the bilinear model or MVF-approach (Metal-Volume-Fraction-approach) for preliminary investigation are simplicity and also its predictions of laminate stiffness EL and yield strength σL,y are quite accurate [4].
The laminate’s longitudinal stiffness EL and the thermal expansion coefficient in fiber direction αL can be predicted by the rule of mixture as a function of the metal volume fraction φm [11].
After the yield point of the steel is exceeded, the laminate´s longitudinal stiffness EL,pl decreases due to the change in rigidity of the metal.
