“…From Figure 4 and Table 3 , feed rate was found to be one of the most influential parameters contributing 51.8% for R a , 42.7% for R max , and 44.3% for R z . This result is anticipated with the very well-known theory of metal cutting that for a specified or stated nose radius, the theoretical surface roughness ( Ra = 0.032

) is principally a function of feed rate [ 36 , 37 ]. The second most influencing parameter was observed in cutting speed with a contribution of 51.8% for R a , 39.6% for R max, and 37.8% for R z .…”

The machinability of materials is highly affected by their hardness, and it affects power consumption, cutting tool life as well as surface quality while machining the component. This work deals with machining of annealed AISI 4340 alloy steel using a coated carbide tool under a dry environment. The microhardness of annealed and non-annealed workpieces was compared and a significant reduction was found in the microhardness of annealed samples. Microstructure examination of the annealed sample revealed the formation of coarse pearlite which indicated a reduction of hardness and improved ductility. A commercially CVD multilayer (TiN/TiCN/Al2O3/ZrCN) coated cemented carbide cutting tool was employed for turning quenched and tempered structural AISI 4340 alloy steel by varying machining speed, rate of feed, and depth of cut to evaluate the surface quality, machining forces, flank wear, and chip morphology. According to the findings of experiments, the feed rate possesses a high impact on surface finish, followed by cutting speed. The prominent shape of the serrated saw tooth chip was noticed at a higher cutting speed. Machined surface finish and cutting forces during turning is a function of the wear profile of the coated carbide insert. This study proves that annealing is a low-cost and economical process to enhance the machinability of alloy steel.

“…The results showed that the copper metal chips in the pad enhanced the productivity by 54.2 % whereas in the aluminium chips filled pad the increase in productivity was 34.23 %. Modi and Modi (Modi and Modi 2020) experimentally analysed the wick pile of jute cloth in the single slope solar still with a double basin. The results revealed that the inclusion of wick material increased the productivity by 21.12 %, 23.71 % on the experiment days.…”

The objective of the work is to investigate the single slope solar still for the enhancement in productivity by the inclusion of optimum weight of palm flower powder of micro-sized in the absorber basin and optimum weight% of micro-Phase Change Material (mPCM) under the absorber basin. In this regard, the effect of different weights of palm flower powder such as 10, 30, 45, 50, 55, 70, 100, 120 and 150 g in the absorber was analysed. The solar still with 50 g of palm flower powder in the absorber increased the productivity by 37.25% whereas, for 10, 30, 45, 55, 70, 100, 120 and 150 g were 11.85, 24.78, 36.1, 36.8, 34.35, 33.05, 10.25 and -20.22% respectively. The effect of different weight% of micro-sized palm flower powder such as 5, 10, 15 and 20 wt%, in paraffin wax, was investigated. The paraffin wax with 20 wt% of micro-sized palm flower powder has a better thermal conductivity of 0.33 W/mK. The experimentation was carried out with 50 g of micro-sized palm flower powder in the absorber basin and 20 wt% mPCM under the absorber basin solar still (PCMPFP-SS) and Conventional Solar Still (CSS). The overall yield of PCMPFP-SS was 4670 ml/m2-day on day 1 and 4250 ml/m2-day on day 2, for CSS it was 3030 ml/m2-day on day 1 and 2800 ml/m2-day on day 2. It was evaluated that the Cost per Litre of PCMPFP-SS was $ 0.025 and $ 0.032 for CSS.

“…It was noted that the system with jute cloth and the minimum depth of basin water had a better output. In the other work (Modi and Modi 2020), the authors studied the in uence of jute cloth as a wick in the solar still. It was observed that the solar still with jute cloth had an increment in yield by about 23.71% compared to CSS.…”

Valarozition and reusing of waste materials before recycling would give sustainable outcomes and reduce the environmental effects. Among various waste materials, automobile tyres are one of the major contributors to environmental pollution while burning as they contain rubber. Hence, worn automobile tyres are procured and made into small pieces before burning to investigate the photothermal absorption in solar thermal applications. In the available solar thermal applications, solar still is the cheap and uncomplicated desalination approach that can be accessible by everyone. However, clean water production is very low in conventional solar still. Therefore, the key intention of this investigation is to improve pure drinking water generation by floating black tyre pieces in the absorber basin of solar still, which has better heat absorption characteristics. The outcomes reported that the clean water production in solar still with tyre pieces (SS-Tyre) is enhanced by 18% more than that of conventional solar still (CSS). The clean water production from SS-Tyre is about 2.7 l/sq.mt, Whereas the distillate output of CSS, is about 2.3 l/sq.mt on two consecutive testing days. In addition to productivity, the cost assessment reported that the cost per litre (CPL) and Payback Time (PT) of SS-Tyre are 19.2% and 20.1% lesser than CSS. Also, the environmental impact assessment of CSS and SS-Tyre reported that the SS-Tyre has 19% more net carbon credit than CSS.
