The electric cars digitization is playing a key and vital role in developing new technology in the automobile market which is transforming the era of automobile sector. Thus, an automobile is changing at the rapid space which is determining the efficiency of automobile vehicles at each and every stage of this sector. Thus, the mechatronic system is playing a major role in determining the efficiency of automobile vehicles. To increase, the efficiency of cars it is necessary to tap the performance of automobile components and to digitize car efficiency according to the industry of 4.0. Thus, car efficiency and performance can be monitored to timely govern the speed and propel the efficiency of auto ancillaries. Thus, mechatronic system is majorly and widely playing a vital role in car efficiency and monitoring the speed at every interval which will enhance the efficiency of automobiles and will give the maximum output by programming the auto ancillaries part which will help to create a new phase of technology which will boost the automobile market. Thus, based on new generation expectation the technology is a key and important role to determine the market potential of electric vehicles and its adaptability according to the Indian market. To meet this benchmark it is essential to develop new digital technology which is a driving factor to propel the growth of the automobile industry.

This research –formulation and performance assessment of fixed oils based cutting fluids in machining operation was done to examine the performance of cutting fluids developed from Shea butter and Neem seed oils (fixed oils) in the straight turning of AISI 1027 steel bar using high-speed steel (HSS) tool. The performance and characteristics of the cutting fluids developed were compared with mineral oil-based cutting fluid- USA metal cutting oil CA2000 (Model 2317 4200N) as the control sample. Generally, mineral oils are costly, not environmentally friendly and so pose a serious problem of disposal since they are not biodegradable. The turning was done at different spindle speeds (530rpm, 750rpm, 1060rpm) and depth of cuts (1.0mm, 1.5mm, 2.0mm) at a constant feed rate of 0.25mm/rev for the mineral oil, formulated cutting fluids and dry turning operation. Each experiment was observed for at least 10mimutes and the cutting oils were fed automatically at the tool-work interface. A thermocouple was used to record the temperature of the tool-work interface at every point. The result shows that a minimum temperature of 31.5oC was obtained when turning at 530rpm/1.0mm and a maximum of 37oC was obtained when turning at 1060rpm/2.0mm using Shea butter based cutting fluid. This shows that Shea butter based cutting fluid was far better than the control sample and Neem seed oil based cutting fluids in term of temperature dissipation. In term of acidic values, the minerals oil base cutting fluid contains more acid of 8.4g/dm3 relative to the two fluids developed from the fixed oils. The viscosity of the developed cutting fluids is better at higher temperatures standing at values of 233.76/227.35cp and 205.83/141.80cp at 40oC/80oC and that of the control sample at 111.34/46cp at 40oC/80oC.
