Abstract—Water miscible cutting fluids are conventionally used to lubricate and cool the machining zone. But issues related to health hazards, maintenance and disposal costs have limited their usage, leading to application of Minimum Quantity Lubrication (MQL). To increase the effectiveness of MQL, nanocutting fluids are proposed. In the present work, water miscible nanographite cutting fluids ...

The demand of Advanced Machining Processes (AMP) is continuously increasing owing to the technological advancement. problems based on AMP are complex in nature as it consisted parameters which interdependent. These also linear and nonlinear constraints. This makes problem may not be solved using traditional optimization techniques. process indispensable use AMP's at its aptness make economical ...

Electrolyte Jet Machining (EJM) has been performed on stainless steel surfaces with the aim of reducing bacterial retention through generation nanoscale surface morphology. Following initial EJM experiments aimed at investigating influence machining depth, speed and current density resulting roughness, three characteristic were produced a 10–18 A/cm2 0.8–8 mm/s to obtain an arithmetic mean heig...

This study investigates dry machining of hypereutectic silicon–aluminum alloys assisted with vortex-tube (VT) cooling. The objective is to reduce cutting temperatures and tool wear by enhanced heat dissipation through the chilled air generated by a VT. A machining experiment, cutting mechanics analysis, and temperature simulations are employed to (1) model the heat transfer of a cutting tool sy...

Currently, micro-abrasive water jet machining has the problem of insufficient processing capacity in central area. To assist with improving efficiency, ultrasonic vibration is introduced. First, based on computational fluid dynamics method, mathematical model three-dimensional shape prediction micro-holes established using a mixed model, standard k-ε discrete phase and dynamic mesh model. The e...

In this study, the effects of process parameters on the geometrical characteristics and the topography were investigated in milling of SS304 material using Abrasive Water Jet machining technique. In addition, optimal control of the input variables for achieving the quality of the channel was determined by using Grey relational analysis. The input process parameters include traverse speed, abras...

Although bidets are widely used in Korea, its effects on anorectal pressures have not been studied in detail in terms of the water settings used. Twenty healthy volunteers were placed on a toilet equipped with a bidet, and anorectal pressures were measured with a manometry catheter inserted into the rectum and anal canal before and after using the bidet at different water forces (40, 80, 160, 2...

Magnesium Products Limited has been very successful in converting from machining magnesium die castings dry to machin'ng with oilin-water emulsions, more commonly called water soluble oils. When machining with water soluble coolants one can expect; 1) excellent fire protection; 2) improved tool life; 3 ) ease of housekeeping, and 4 ) improved productivity. Problems previously encountered with w...
