Context: Measurement programs have been around for several decades but have been often misused or misunderstood by managers and developers. This misunderstanding prevented their adoption despite their many advantages. Objective: In this paper, we present the results of an empirical study on the impact of a measurement program, MQL (“Mise en Qualité du Logiciel”, French for “Quality Software Dev...

Cutting fluids are frequently aim to enhance machinability through cooling, lubricating and flushing actions. However, their use in machining creates major concerns terms of health footprint environmental effect. human throughout lifecycle. To diminish these problems, alternative methods were used, namely; dry cutting minimum quantity lubrication. This research also will investigate the effect ...

In the new global economy, consumption has become a central issue for many fields of industries. This project work studied on the effectiveness of pulse duration of supercritical carbon dioxide (SCCO2) in machining performance in terms of cutting temperature, cutting force and surface roughness in turning AISI 1045 medium carbon steel by uncoated cemented carbide insert. Pulse mode reduces the ...

Abstract Minimum quantity lubrication (MQL) is a relatively efficient and clean alternative to flooding workpiece machining. Electrostatic atomization has the merits of small droplet diameter, high uniformity size, strong coating, hence its superiority pneumatic atomization. However, as current research hotspot, influence jet parameters electrical on average diameter droplets not clear. First, ...

Titanium alloys are used in aeronautics and the shipbuilding industry for their good intrinsic properties, namely low density (40% less than steel), very mechanical properties resistance to corrosion. The purpose of this study is optimize cutting conditions during turning Ti-6Al-4V titanium alloy with Minimum Quantity Lubrication (MQL) leading minimize surface roughness (Ra). tests were carried...

The purpose of this comparative study is to improve the predictive accuracy cutting force during turning Ti-6Al-4V on a lathe machine. By optimizing machining process parameters such as speed, feed rate, and depth cut, in can be improved significantly. Cutting one crucial characteristics that must monitored order enhance tool life surface finish workpiece. This paper based experimental dataset ...

wind gearbOx technOLOgy is developing at a fast pace, not least due to operators demanding ever more power and efficiency. Experience has shown that the lubricant used is a crucial factor in meeting the wish for ever-increasing performance. Besides strictly technical requirements, aspects of economy and ecology are receiving more and more attention in lubricant selection. The technical requirem...

The model of surface grinding with a nanoparticle jet flow of MQL was established. The surface grinding thermal stress of three workpiece materials, namely, 45 Steel, 2Cr13, and nano-ZrO2 dental ceramic, were numerically simulated. Results show that dry grinding generates larger tensile stress, whereas MQL grinding generates larger compressive stress. The finished surface of workpiece produces ...
