Fabrication and Machining of Metal Matrix Composites: A Review

Abstract: Intrinsically smart, metal matrix composites (MMCs) are lightweight and high-performance materials having ever expanding industrial applications. The structural and the functional properties of these materials can be altered as per the industrial demands. The process technologies indulged in fabrication and machining of these materials attract the researchers and industrial community. Hybrid electric discharge machining is a promising and the most reliable nonconventional machining process for MMCs. It exhibits higher competence for machining complex shapes with greater accuracy. This paper presents an up-to-date review of progress and benefits of different routes for fabrication and machining of composites. It reports certain practical analysis and research findings including various issues on fabrication and machining of MMCs. It is concluded that polycrystalline tools and diamond-coated tools are best suitable for various conventional machining operations. High speed, small depth of cut and low feed ra...

Impact of congestion on greenhouse gas emissions for road transport in Mumbai metropolitan region

Abstract: Traffic congestion on roads not only increases the fuel consumption but consequently leads to increase in carbon dioxide emissions, outdoor air pollution as well as increase in the exposure time of the passengers. We analyse the greenhouse gas emissions for road transport sector in Mumbai Metropolitan Region (MMR) using fuel consumption and the vehicle kilometre travelled methods. In addition, by conducting traffic survey on four major roads in MMR, the congestion factor was established to estimate the share of greenhouse gas emissions from the road transport sector that can be attributed to traffic congestion.

Residual Stresses, Surface Roughness, and Tool Wear in Hard Turning: A Comprehensive Review

Abstract: Hard turning is used in the manufacturing industry as an economic alternative to grinding, but the reliability of hard turning processes is often unpredictable. The main factors affecting the reliability of hard turning are surface integrity and tool wear. In the present study, an attempt has been made to investigate the effect of cutting parameters on surface roughness, tool wear, and residual stress distribution in hard turning. This article brings out the comprehensive analysis of the effects of cutting parameters on surface roughness, residual stress, and tool wear.

Influence of cutting parameters on tool wear and surface roughness in hard turning of AISI H11 tool steel using ceramic tools

Abstract: In machining of parts, surface quality is one of the most specified customer requirements. Major indication of surface quality on machined parts is surface roughness. There are various machining parameters which have an effect on the surface roughness, but these effects have not been adequately quantified. In order for manufacturers to maximize their gains from utilizing finish hard turning, accurate predictive models for surface roughness and tool wear must be constructed. This paper utilizes response surface methodology (RSM) for modeling to predict surface roughness and tool wear for variety of cutting conditions in finish hard turning. The experimental data obtained from performed experiments in finish turning of hardened AISI H-11 steel have been utilized. Decrease in feed rate and increase in cutting speed resulted in significant increase in surface quality. However, increase in cutting speed also produced relatively higher tool wear. Also depth of cut did not significantly affect the tool wear and surface roughness.
