Energy efficient machining of Ti–6Al–4V

Modelling and multiobjective optimization for productivity improvement in high speed milling of Ti–6Al–4V using RSM and GA

“…Polynomial fit was done between trades off points for developed relationship between MRR and power consumption as shown in Eq. (12). Equation (12) can also provide power consumption for desired value of MRR ( Fig.…”

“…Constant power consumption in machine tool includes power required for chip removal, coolant pump, CNC controller, automated tool changer, condition monitoring device and so on. Variable power consumption includes machining of material and feed acceleration and deceleration which accounts for 30% of total power consumption of machine tool [10][11][12]. Variable power consumption depends on material properties and machining and tool conditions which can increase in case of super alloys like titanium alloys.…”

“…Variable power consumption depends on material properties and machining and tool conditions which can increase in case of super alloys like titanium alloys. Denkena et al [12] performed milling of titanium alloys to see the effect of coolant flow rate on machining power. They found that as the process power increases, flow rate should also be increased.…”

A method integrating Taguchi, RSM and MOPSO to CNC machining parameters optimization for energy saving

“…Approximately 6-40% of the total energy consumption can be saved together with the optimization of cutting parameters, tools and tool path. As demonstrated by Denkena et al (2015), energy of the spindle motor can be saved to more than 40% by changing the process parameters at the same material removal rate. Therefore, it is imperative to have a thorough study of the dependence of energy efficiency on machining parameters, and some feasible and reliable optimization methods for energy saving are required to be systematically developed.…”

Electrohydrodynamic Atomization for Minimum Quantity Lubrication (EHDA-MQL) in End Milling Ti6Al4V Titanium Alloy

“…Together with poor thermal conductivity, these material properties are also responsible for making Ti6Al4V a difficult-to-machine material [3]. With its high strength and toughness, a large amount of energy is required during machining operations [4]. The majority of the energy used for material cutting transforms into heat at the cutting zone.…”
