Effectiveness Improvement in Manufacturing Industry; Trilogy Study and Open Innovation Dynamics

“…The cutting speed, expressed in meters per minute (m/min) or feet per minute (ft/min), is the path traveled by a point on the cutter. Literature reveals that using extremely slow cutting speed is unviable for production and extremely high cutting speed is unworkable for economical production [40]. The most viable cutting speed must be chosen for a workpiece tool interface without affecting performance and economy [41,42].…”

Energy, Environmental, Economic, and Technological Analysis of Al-GnP Nanofluid- and Cryogenic LN2-Assisted Sustainable Machining of Ti-6Al-4V Alloy

“…Besides dry machining processes, some cooling/lubricationassisted machining such as the flood cooling approach, near dry lubrication, high-pressure cooling, solid lubrication integrated with sprayed cooling, oil-water emulsion, nanofluid and hybrid nanofluids approaches are employed at machining workshops to machine hard and difficult-to-cut materials [21]. In another study, Khan et al [22] developed new energy-integrated cost models for nanofluid-assisted machining. The authors holistically investigated the 3E-based (Energy, Environment, Economy) sustainability of the hybrid Al-GnP nanofluid-assisted machining process.…”

“…Nanofluids were prepared with different volumetric concentrations and used immediately after preparation. It is worth mentioning that the thermal conductivity, viscosity, and coefficient of friction of the hybrid nanofluid (Al-GnP) were measured before application [22]. The Zeta potential of the Al-GnP nanoparticle was found to be 45 mV, which showed the good stability of the nanofluid.…”

“…With the increase in pressure, energy consumption (E m ) initially increases; however, it starts decreasing at the highest level of pressure. The quality of nanofluid is highly influenced by the concentration of nanofluid [22]. The effect of nanofluids with various fractions of nanoparticles on cutting power and machining energy is shown in Figure 8.…”

Ecological, economical and technological perspectives based sustainability assessment in hybrid-cooling assisted machining of Ti-6Al-4 V alloy

“…In another work, Hegab et al, (2018) used the empirical sustainability assessment model to evaluate the effect of metal cutting conditions on environmental aspects [22]. The same model was also implemented in the work of and the environmental assessment was done on selected cooling conditions [23]. In literate, some artificial intelligence methods were also implemented to improve the process performance [24][25][26].…”
