    Abstract: The current study demonstrates the effect of minimum quantity cooling lubrication (MQCL) using MoS2 emulsion-based nanofluid on hard milling of SKD tool steel (52-60 HRC) with coated cemented carbide inserts. The input machining parameters including nanoparticle concentration, cutting speed and hardness on cutting forces are investigated in term of... Show More

    Abstract: This is the last part of the series studying the fitted hydrostatic thrust spherical bearing. It handles an unconventional design of this type of bearings. The conception of this design is to break the rules controlling the bearing restrictions, where it is believed that without restrictors no hydrostatic bearing could be got (axiom). The paper foc...
