“…Regression analysis is used for expressing the results of experiments quantitatively in terms of an empirical model, to facilitate understanding, interpretation and implementations [9]. The regression analysis for surface roughness is shown in table 10.The value of adjusted R square is 77.15% and is a decrease of 9.41 % R square value indicate that the degree of closeness of variable with best fit line.…”

“…To thoroughly investigate this process, a series of experiments were performed to determine the difference between wet (flood application) and dry machining on such characteristics as workpiece temperature, cutting forces, BUE, bore distortion, and surface finish. (5) While the presence of cutting fluid was shown to have little impact on cutting forces, BUE, and surface finish, observable differences in workpiece temperature were present, as shown in Figure 2. These results clearly demonstrate the heat transfer capability of cutting fluids during the boring process.…”

“…Thus, Equation 3 may be evaluated and after multiplying by R, the actual film thickness is obtained. The actual maximum fluid flow rate, in our case q max , can be expressed as: q max = LQωR 2 [5] In summary, if the applied fluid flow rate, q, is larger than q max for a given rotational speed, then some fluid will drain from the workpiece and the amount of the fluid that forms the ligaments (q l ) will equal q max . On the other hand, if the fluid flow rate, q, is smaller than q max , the fluid flow rate to form the ligaments will be q l = q.…”

The use of cutting fluids in machining operations is being carefully scrutinized by industry for several reasons, including its overall cost in the manufacturing process and its impact on worker health. Given the concerns associated with the use of cutting fluids, a number of experimental and analytical research efforts are being conducted to gain an understanding of the role of these fluids in various machining processes. The knowledge gained by this research will aid in the development and implementation of strategies to reduce or eliminate the negative effects of cutting fluids, while maintaining their beneficial role. This article presents the results of designed experiments focused on determining the significant variables that influence air quality during turning operations, as well as characterize the aerosol emissions associated with wet and dry turning. Air quality is characterized by measuring the mass concentration and particle size distribution of the dust and mist created during a set of machining experiments. The relative importance of vaporization/condensation and atomization as mist-generating mechanisms is also explored. The experiments revealed that spindle speed has a dominating effect on both mist mass concentration and aerodynamic particle size. Analytical models are presented that predict the average droplet size of the mist generated by atomization and are used to investigate droplet size trends for various cutting fluids and machining parameters. The results predicted by the models are consistent with the expected trends.

AbstractPurpose -The purpose of this paper is to study the tribological behavior and mechanism of water-soluble bismuth dithiophosphate as the additive of water-based cutting fluid in aluminum alloy tapping. Design/methodology/approach -Comparable investigation has been made on the lubrication performance of bismuth dithiophosphate and sodium dithiophosphate in aluminum alloy tapping. The aluminum alloy-machined surface finish was observed on scanning electron microscope. The films on the work-piece-machined surface and the tap tool working surface were analyzed by X-ray photoelectron spectroscopy. Findings -The results indicated that the water medium containing 1 wt% the prepared water-soluble bismuth dithiophosphate exhibited better tapping efficiency than the liquid paraffin containing 2.5 wt% chlorinated paraffin and 2.5 wt% sulfurized olefin. The bismuth sulfide component in the reaction film on the tap working surface plays a leading role in elevating the tapping efficiency and improving the machined surface finish.Research limitations/implications -The paper is restricted to the lubrication performance of bismuth dithiophosphate as the water-based cutting fluid additive in 2024 aluminum alloy tapping. Practical implications -The test method adopted is very close to the machined method applied in industry. The test results show that the bismuth dithiophosphate can obviously improve the tapping efficiency and the machined surface finish. Thus, it can be applied to the aluminum alloy cutting in automotive and aviation. Originality/value -An attempt has been made to identify the chemical reaction film sourced from bismuth element and dithiophosphate group on the work-piece-machined surface and the tool working surface and their contribution to enhancing the...
