“…Similar results were obtained by many other researchers and reported that during the machining of SiCp reinforced composites with both carbide and PCD inserts 5,7,12 . At lower cutting speeds the surface roughness is high due to the inability of the cutting tool to cut these particles, therefore, a high cutting speed is required to machine this composite 13 . Sometimes during turning, it was observed that the surface roughness value is abruptly higher than the trend value.…”

“…This was attributed to high temperature in the cutting zone. Higher feed rate values increases temperature and this cause to decrease bonding effect between SiC particles and Al alloy matrix 13 . The surface roughness values for the graphitic composites are higher compared to SiCp reinforced 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.

“…Similar results were reported by Sahin and Sur [2], who concluded that tool life decreased with increasing cutting speeds and the major form of the tool wear was the mild abrasion and edge chipping on the flank face of the tool. Sahin et al [1] showed that, in machining of various volume fractions of alumina particles, the flank wear is associated with BUE formation in addition to broken layer of coated material. They suggested that triple-layer coating was more resistant than double-layer coating based on tool life.…”

“…In addition to the tool coatings, no optimization has been done on the presentation of the tool to the material. Effects of approach geometry (i.e., rake, lead) have not been incorporated into past studies nor have the geometry of the cutting edge of the insert [1,2]. The main problem when machining MMC is the extensive tools wear caused by the very hard and abrasive reinforcements.…”

A wide range of particulate metal matrix composites (PMMCs) of alumina and aluminum powders was formed using powder metallurgy techniques followed by extrusions at various extrusion ratios. The machining characteristics of the extruded PMMC were investigated. Results showed significant effects of weight fractions of reinforcement and extrusion ratios on tool wear and surface integrity of machined surface. The wear rate of cutting tool decreased rapidly with increasing the cutting parameters: cutting speed, feed, and depth of cut, however cutting speed is shown to be more effective. Sudden breakage of tool inserts occurred when the experiment started at high cutting speed. Wear rate has also decreased by decreasing volume fraction of reinforcement particles. Coating carbide tools have significantly improved the tool life. Coated tools showed 5% decrease in flank wear size compared to uncoated tools. This was valid within tested range of weight fractions and extrusion ratios. The surface finish of machined surfaces deteriorated when coated carbide tools were used. However, surface finish did not change significantly when volume fractions or extrusion ratios were altered.

Metal matrix composites (MMC) have become important materials in many technical fields. But above all there is a high amount of failures due to alternating stresses because of temperature changes. In this investigation the thermal fatigue behaviour of two metal matrix composites with different particle contents and their base material without particles are compared. It is shown that there are three main parameters influencing lifetime: the maximum temperature of the cycles, the particle content and the particle size. An increasing of these parameters means a decreasing of the cycle numbers before damage occurs.
