“…The maximum surface roughness value appeared in the turning of the 10% Al 2 O 3 particles reinforced composite with particle size of 16 µm. Dabade et al 14 reported while machining metal matrix composites with CBN tools with and without wiper on cutting edge. The microstructural analysis of the machined surface showed the number of feed marks, pits and cracks on the machined surface are significantly reduced using the wiper inserts, especially in the case of Al/SiC/30p composites.…”

This study presents an experimental investigation on surface roughness and chip formation in turning of Al 2219/15SiCp and Al 2219/15SiCp-3Gr (hybrid) composites. Experiments were conducted with different cutting conditions using carbide, coated carbide and polycrystalline diamond (PCD) tools. The results reveal that the surface roughness values are less for coated carbide tools compared to carbide and are minimum for PCD tools. The incorporation of graphite in Al 2219/15SiCp composite increases the surface roughness. This is due to smearing and removal of softer and amorphus graphite particles on the surface of the specimen, creates pits on the machined surface which increases the surface roughness values. The graphitic composite produced discontinuous chips leads to easy machining. PCD tool performs better than carbide and coated carbide tools.

“…Palanikumar and Karthikeyan [3] investigated the factors influencing the surface roughness on the machining of Al/SiC particulate composites, using tungsten carbide tool inserts (K10). Dabade et al [11] studied the surface integrity as a function of process parameters and tool geometry by analysing cutting forces, surface finish, and microstructures of the machined surfaces on Al/SiC/10p and Al/SiC/30p composites using cubic boron nitride (CBN) inserts. Basheer et al [12] presented a model to predict the surface roughness in precise machining of metal matrix composites, using PCD tools with respect to the size and volume of reinforcement, tool nose radius, feed rate, and the depth of cut.…”

“…They found that the feed rate has greater influence on surface roughness than cutting speed and volume fraction of SiC. Dabade et al (Dabade et al,2007) carried out cutting experiments using CBN inserts with and without wiper on cutting edge to study the integrity of the machined surface on Al/SiCp composites. Their microstructural analysis showed that the number of feed marks, pits and cracks on the machined surface is significantly reduced using the wiper inserts.…”

During machining Al/SiCp composites, the machined surface takes on many defects such as grooves, pits, voids and protuberances, which greatly affect the characterization parameters of surface topography. However, a detailed investigation of the formation mechanism of surface defects in machining Al/SiCp composites is still lacking, and few surface roughness evaluation methods have been developed for separating the surface defects from roughness. In this paper, the formation mechanism of surface defects is revealed, and a roughness extraction method based on DT-CWT is established to extract the surface defects from roughness and conduct a roughness evaluation on the machined surface of Al/SiCp composites. Compared with the least-square method and Gaussian filter, the roughness extraction method based on DT-CWT has higher stability and can effectively distinguish between surface roughness and surface defects. According to the surface roughness evaluation based on the roughness extraction method, it is found that the surface roughness value of 2024Al/SiCp composite is lower compared to 6063Al/SiCp composite.
