“…Consequently, the application of MQL technique is considered as an outstanding alternative compared to normal cutting fluid application. The effect of MQL parameters on machining is the most saliency such as nozzle elevation angle, distance from the nozzle tip to the machined surface, lubricant flow rate and air pressure [13][14][15]. Also, MQL parameters also have different technological parameters such as nano-particle, vegetable oil, cryogenic, and so on.…”

AISI 1050 steel circular pocket milling under minimum quantity lubrication (MQL) surroundings including nozzle elevation angle, lubricant flow rate, air pressure and cutting speed was studied. The machined surface quality (Ra) was evaluated for Up-milling side and Down-milling side. In this study, to obtain an manifest explanation on the pivotal effective parameters of MQL surroundings and cutting speed on the machined surface quality (Ra) through analyzing Taguchi L9 (34-2) approach and ANOVA calculation to identify those parameters, by utilizing the experimental outcomes to interpret three-dimensional (3D) surface plots and the diagrams of Signal-to-Noise ratios and major impact plots of Mean. The obtained outcomes of optimal operating parameters indicated that the pivotal effective parameters of MQL surroundings are nozzle elevation angle and lubricant flow rate on the machined surface quality. Simultaneously, a quadratic mathematical paradigm generated by using response surface design (RSD) and desirableness function evaluation were utilized to forecast the optimal values of the machined surface quality compared to Taguchi method. The results unveiled that the optimal values of the machined surface quality are adjacent to experimental attained values. The machined surface quality has been significantly improved using MQL surroundings.

“…They found that spraying the cutting fluid at the exit point (disengagement point) resulted in the longest tool life due to elimination of chip adhesion. Yuan et al 8 evaluated the effect of the nozzle position in an end milling process of 50CrMnMo, a structured alloy steel. The position of 60° away from the disengagement point led to prolonged tool life.…”

High-speed machining, the need to reduce environmental impact and manufacturing cycle time have promoted the use of minimum quantity lubricant in mechanical machining. However, in minimum quantity lubricant, where a small quantity of cooling lubricant is delivered to the cutting zone, the sensitivity of machining performance to nozzle position has hardly been explored in research or noted in industrial practice. In this study of conventional versus high-speed machining, the focus was on a systematic study of the effect of nozzle position on tool wear. This study elucidates the effect of spindle rotation speed on the sensitivity of nozzle location in order to enhance machining performance. This work provides some fundamental information regarding the position and orientation of the nozzle in order to maximise the benefits of machining using minimum quantity lubricants. This work is of significant importance for the repeatability of minimum quantity lubricant machining operations and to promote longer tool life in particular for machine shops where nozzles are currently randomly oriented to the cutting zone.

In the current paper, some aspects regarding the quality of the surface machined under different lubrication conditions is being assessed: cutting under a jet of cutting fluid, minimum quantity lubrication cutting, dry cutting. The objective was to assess the results obtained after MQL cutting in comparison with dry cutting and cutting under a jet of cutting fluid. The variables of the cutting regime were the feed rate and the type of milling (climb and conventional). This study has an important ecological impact over the use of cutting fluids.
