“…The angle of the cutting edge of the hob plays an important role in the teeth cutting operation on the gear blank. The angle of the teeth of the hob decides the pitching angle on the gear blank [4] [20]. The parameters which are considered while the performing the gear hobbing operation are indexing, angle between the axis of gear blank and the hob, feed rate [19].…”

Gear is mechanical component mounted on the shaft to transmit the power from one shaft to another. Gear is mostly manufactured by using the hobbing process. In hobbing process the tooth are cut on the gear blank with the help of the indexed hobs. The hobbing process the gear blank and the hob are rotated with each other simultaneously with certain speed. The rotating movement of the hob and the blank creates the cuts and forms the tooth on the gear blank. In the process of the gear hobbing the rotating speed of the hob and rotating speed of the gear blank plays an important role in teeth cutting operation and the formation of the teeth on the gear blank. The rotating speed of the hob also determines the tool life of the hob. As the hob rotates with high speed the wear occurs in the hob due to variation of the cutting force with respect to the cutting speed. This paper will conclude how the variation of the cutting speed of the hob and gear blank affects the cutting of tooth on the gear blank.

“…In our reported RSM-CCD approach, the R-square value is observed to be 98% which signifies how effectively the predictor factors in the model can account for variances in the dependent factor and the ease of response very well. As a result, the model can be said to have good practical significance [76][77][78]. Adequate precision (AP) determines the signal-to-noise ratio, and a ratio > 4 is considered to be desirable [79].…”

In this work, we reported the transesterification of soybean oil (SO) to biodiesel using a basic CaO nanocatalyst produced by sequential calcination, hydration, and dehydration of waste snail shells. Response-surface methodology (RSM) and a central composite design (CCD) were used to predict several optimization parameters. 1H-NMR confirmed that 98.5% of the SO was transformed into methyl ester biodiesel. Under the optimal reaction parameters of catalyst loading of 6 wt. %, methanol to oil molar ratio of 8 : 1, reaction duration of 3 h, and temperature of 70°C, an excellent biodiesel yield of 96.1% was obtained. The transesterification of SO to biodiesel displayed a significantly low activation energy (30.45 kJ mol-1), whereas, the turnover frequency of the transesterification reaction was found to be 0.0063 mol g-1 h-1. The catalyst showed excellent stability and was consecutively used for six cycles without a significant decline in catalytic activity. Based on life cycle cost analysis (LCCA), the estimated cost for producing 1 kg of biodiesel in this study comes out to be just $0.935, signifying its strong potential for widespread commercial use.
