TL;DR: In this article, an investigation has been undertaken to study the compatibility of cutting materials in dry machining of aluminium and Al-Si alloys, and the results of turning test, SEM pictures and chip morphology investigation of the cutting tool after machining clearly reveal the inefficiency of TiC, TiN, TiB2, Al2O3, and AlON.
Abstract: An investigation has been undertaken to study the compatibility of cutting materials in dry machining of aluminium and Al–Si alloys. Mono or multilayer coated carbide tools with a top coating of TiC, TiN, TiAlN, Al2O3, TiB2, MoS2 etc. on WC–Co inserts already made a major breakthrough in dry machining of ferrous materials. But in contrast dry machining of aluminium and Al-alloys is a great challenge. But wide application of aluminium different parts has increased the need to find out the correct cutting tool. Experimental results of turning test, SEM pictures and chip morphology investigation of the cutting tool after machining clearly reveals the inefficiency of TiC, TiN, TiB2, Al2O3, and AlON in dry machining of aluminium. This is because of the formation of very large amount of metal built-up in both rake and flank surface leading to high magnitude of cutting forces and high roughness of the work-piece during machining. The natural diamond and polycrystalline diamond (PCD) can be used as a cutting tool, when the required shape is attached on the edge/tip for machining non-ferrous materials. But both of them are limited for finishing cut because of high cost. So CVD diamond coated tool is a better option to machine these materials. CVD diamond coated tool was free from built-up edge formation leading to clean cut, low magnitude of cutting forces and improved surface finish of the work-piece. However, performances of the diamond tool depend mainly on adhesion of the diamond coating with the carbide substrate.

TL;DR: In this paper, the effect of temperature on PV electrical efficiency, construction of Photovoltaic-Thermal (PV/T) module, historical development of PV/T, about different types of PV and thermal modules developed around the globe along with performance of developed PV/Ts, effect of operating parameters and methods of thermodynamic management are reviewed and presented.
Abstract: Carbon dioxide emissions from burning fossil fuels are believed to be the main factor for alarming rise in global temperatures. Conference of Parties 21 held at Paris in the year 2015 strictly warned and asked the nations to reduce their greenhouse gas emission level. This makes the nations to adopt renewable energy technology to substitute burning fossil fuels. Solar energy due to its accessibility and affordability leads the renewable energy application race. Even though Photovoltaic (PV) technology is mature but the effect of temperature on its efficiency is considerable, which opens up new front of research where combination of PV and thermal absorber is focussed to harness thermal energy which otherwise negatively affect the PV electrical efficiency. In the proposed study starting from the effect temperature on PV electrical efficiency, construction of Photovoltaic-Thermal (PV/T) module, historical development of PV/T, about different types of PV/T's developed around the globe along with performance of developed PV/T's, effect of operating parameters and methods of thermodynamic management are reviewed and presented. The study emphasised on the use of nano fluid and phase change material to harness maximum thermal energy from the system, also includes an insight into commercially available PV/T modules across the globe. This paper presents enviro-economic evaluation of PV/T systems developed by various researchers and also enumerated thermodynamic methods for evaluating system efficiency, which includes both energy and exergy analysis. This paper also provides the necessary information about the requirement of future research in PV/T.
