Abstract
Metal matrix composites (MMCs) are composed of non-metallic reinforcements (i.e., ceramic) in metal matrices which feature high toughness, wear and fatigue resistant and relatively light-weight. One of the metallic composites with remarkable mechanical properties is titanium metal matrix composite (Ti-MMC) that is considered as an alternative to nickel-based alloys. Despite excellent mechanical and physical features of Ti-MMC, due to high price and presence of hard and abrasive ceramic particles in metal matrices, machining, and machinability of Ti-MMCs is a complex subject. Knowing that very limited studies are available on machining Ti-MMCs under various flow rates and lubrication modes, adequate knowledge about the effects of cutting parameters and lubrication modes on machining attributes is a critical issue. Therefore, this study intends to present the turning of Ti-MMC under dry and semi-dry modes at various levels of flow rates. Effects of cutting parameters on several machining attributes including cutting forces, surface roughness, and particle emission will be presented in the course of this study.
