In this research, an experimental investigation was carried out to investigate the interaction between various turning parameters and different minimum quantity lubrication (MQL) flow rates compare their effects on chip shape surface integrity characteristics in low speed high of AA6061-T6. The included cutting speed, feed rate, depth cut. comprised 3.5 $$\mathrm{ml}/\mathrm{min}$$ , 10 15 cons...

Theoretical Analysis on the profile of slider in reciprocating compressor has been presented based on the hydrodynamic lubrication. Theoretical Analysis calculates fluid film pressure, attitude angle, frictional force, and minimum film thickness in normal condition for comparing two different profiles of slider. The calculated results show that the profile of slider plays an important role in t...

An investigation is made into the effects of liquid carbon dioxide (LCO2) cooling, minimum-quantity lubrication (MQL) and cutting speed in drilling. Experimental measurements torque, thrust force temperature are over a wide range process operating conditions. The resulting empirical models used to quantify individual contributions controlled parameters on drilling performance, facilitate temper...

Novel “sub-zero” cooling methods are an emerging technology employed in machining of aerospace alloys that has been the focus substantial ongoing research. A series different media have used effort to decrease friction and amount heat generated cutting zone. This study focused on use supercritical carbon dioxide (scCO 2 ) as a coolant face milling titanium alloy Ti-6Al-4V. Traditional flood emu...

Abstract This paper presents the study of finishing, repair, and maintenance turning operations gamma titanium aluminide (?-TiAl) parts from aeronautic industry, with aim to evaluate different sustainable lubrication/cooling environments, including a newly developed synthetic ester water-based metalworking fluid (EcoMWF) replace mineral-based MWF (MWF). The systems considered in this work are d...

in order to reduce wear in gudgeon pin, bush and piston boss lubrication is done. oil used in national engine species was 10w40 with dynamic viscosity 5.5 mpa.s at 140 °c (the working temperature). in order to complete investigation the oil film hydrodynamics analysis in small end of connecting rod, a real full model engine with four cylinders has been simulated by avl excite5.1 software. in th...
