Optimization and Modelling of Performance Parameters in Turning Aisi 1029 Steel Using Hybridized Shea Butter and Baobab Seed Oil Based Cutting Fluids (Published)
This research Optimization and Modelling of performance parameters in turning AISI 1029 steel using hybridized Shea butter and baobab seed oil cutting fluids used the blends of Shea butter (SB) and Baobab seed oil (BSO) in the ratio of 70%SB: 30%BSO (SBBSOCFI), 60%SB:40%BSO (SBBSOCFII) and 50%SB:50%BSO (SBBSOCFIII as base oils to formulate cutting fluids to be used in turning operation. Cutting speed (CS), depth of cut (DC), feed rate (FR) and cutting fluids (FT) were the machining parameters while temperature and metal removal rate (MRR) were the response variables (performance parameters). The experiment was designed using Taguchi OA Design of experiment (DoE)) taking four (4) factors at three (3) levels. Optimization of the performance parameters was done from Design Expert version 11, ANOVA was used to determine the statistical difference between mean of the variables and Signal-to-Noise ratio (SNR) was used to analyze the results. Besides, mathematical models for the process parameters were developed to predict values of the response variables. From the results obtained SBBSOCFIII produced the least tool-work interface temperature of 39.81OC at cutting conditions 50mpm, 1.00mm and 0.750mm/rev. Similarly, SBBSOCF1 achieved the highest MRR of 69993.7mm3/min at 90mpm, 1.0mm and 0.75mm/rev. It can now be said that these hybrid cutting fluids which are bio oils based cutting fluids that have good prospect for cutting fluids developments and some other industrial applications.
