“…Flooding of the machining zone with cutting fluids of about 100 L/h is a common practice in conventional machining as it provides cooling effect and lubrication [61]. Depending on the choice of cutting fluid, the heat generated at the cutting area is effectively cooled using water as cutting fluid for example, the continuous flooding helps in effectively removing chips which also conduct away the heat generated [10]. Should the fluid contain lubricant like soluble or straight oil as water cannot lubricate effectively, it reduces the coefficient of friction at the tool-chip interface [8,10].…”

“…However, the authors reported that this approach was not cost effective and may not be sustainable. Overall, there is need for more studies involving optimisation of MQCL technique because studies from several authors show that machining outcomes are significantly dependent on cutting parameters, flow rate of the fluid as well as alloy chemistry [10,60,72,73].…”

“…So, about 80% of the heat generated at the interface is conducted by the tool, hence causing rapid tool wear [6][7][8][9]. The low elastic modulus of titanium alloys leads to high spring back which causes vibrations during machining and ultimately results in poor surface finish [8,10]. This poor surface finish is not desirable in machined titanium workpiece as they may contain stress raisers like cracks [3,4] which would initiate fatigue failure under inservice conditions.…”

Machining is one of the major contributors to the high cost of titanium-based components. This is as a result of severe tool wear and high volume of waste generated from the workpiece. Research efforts seeking to reduce the cost of titanium alloys have explored the possibility of either eliminating machining as a processing step or optimising parameters for machining titanium alloys. Since the former is still at the infant stage, this article provides a review on the common machining techniques that were used for processing titanium-based components. These techniques are classified into two major categories based on the type of contact between the titanium workpiece and the tool. The two categories were dubbed conventional and non-conventional machining techniques. Most of the parameters that are associated with these techniques and their corresponding machinability indicators were presented. The common machinability indicators that are covered in this review include surface roughness, cutting forces, tool wear rate, chip formation and material removal rate. However, surface roughness, tool wear rate and metal removal rate were emphasised. The critical or optimum combination of parameters for achieving improved machinability was also highlighted. Some recommendations on future research directions are made.

The novel controllable behaviour of magnetorheological (MR) fluid is the backbone of magnetorheological fluid-based finishing processes. MR fluid-based finishing processes facilitate better control over finishing forces as the stiffness of MR finishing fluid used in these processes can be controlled in accordance with the applied magnetic field and MR finishing fluid composition. Therefore, a detailed experimental investigation was carried out to find the effect of MR finishing fluid constituents on its yield stress through the Taguchi Design of Experiments. Rheological data obtained from a magneto-rheometer (MCR-102) was characterised by using Bingham plastic, Herschel-Bulkley and Casson's fluid constitutive modelling. The coefficient of regression (R 2) values of Herschel-Bulkley model were found to be best suited for all compositions of MR finishing fluid. Analysis of variance (ANOVA) has been used to find the contribution of selected parameters for improving the response characteristics. The optimized fluid has been then used for the finishing of biocompatible stainless steel AISI 316L, and the finishing results show that the average surface roughness value decreases down to 58 nm.
