“…Because of the above mentioned reasons, dry machining would be of maximum interest [5][6][7][8][9], but this is somehow nonfeasible for aluminium alloys, and generally for light alloys, due to the trend of these materials to adhere to the tool edges. This phenomenon is known as built up layer (BUL) and it involves decrease of tool life [10].…”

“…MQL is able to produce a similar result as the flood application when efficiently applied to the cutting zone, resulting in almost dry chips. The results obtained by Popke et al [10] with minimum quantities of cutting fluid applied during drilling were excellent compared with the typical flood-type application. Klocke and Eisenblätter [6] studied atomizing the lubricant directly into the cutting zone.…”

Due to its excellent mechanical strength and corrosion resistance at high temperatures, Inconel 718 alloy has several applications in the aerospace and nuclear industries. This austenitic material promotes rapid hardening by selfhardening during machining, and its low thermal conductivity leads to high temperature in the cutting zone. As heat increases, cutting tool wear accelerates, compromising the final quality of the machined workpiece. These factors lead to Inconel 718's difficult machinability and influence the presence of surface residual stresses due to thermal and mechanical loads during machining. To address a knowledge gap pertaining to Inconel 718 end milling, this study conducts a series of experiments to gather a set of important results. The optimum cutting speed is calculated by high-efficiency range analysis using the conventional flood method; then, this calculated speed was adopted in the minimum quantity lubrication (MQL) experiments, and the results of the two methods were compared. For the same cutting conditions, the cutting fluid method did not influence the cutting force and surface hardness results, which remained constant along the cutting length. In the MQL application mode, the flow rate influenced tool wear, which was greater than for the flood mode throughout the cutting length. The flood method resulted in improved residual stresses in the longitudinal and transverse directions when compared with MQL, obtaining compressive residual stresses for longer cutting lengths. Surface roughness values were similar for the two lubrication methods up to 50 mm, from which the flood method values increase. Based on the results, the flood mode was found to be the preferred method for milling Inconel 718.

“…A great deal of research has been conducted at both system-level and process-level to evaluate the environmental impacts of machining and to find practical methods to reduce these impacts [8,9,10]. Environmental impacts of machining processes happen through use of energy, waste materials and chemical emissions [8].…”

Machining is one of the major activities in manufacturing industries and is responsible for a significant portion of the total consumed energy in this sector. Performing machining processes with better energy efficiency will, therefore, significantly reduce the total industrial consumption of energy. In this paper, a framework is presented to validate the introduction of energy consumption in the objectives of process planning for CNC machining. The state of the art in process planning and energy consumption in manufacturing research is utilised as a basis for the framework. A mathematical representation of the logic used is presented followed by two sets of experiments on energy consumption in machining to validate the logic. It is shown that energy consumption can be added to multi-criteria process planning systems as a valid objective and the discussion on using resource models for energy consumption estimation concludes the paper. These experiments represent a part test procedure machining proposal for the new environmental machine standard IS014955 Part 3.
