Material removal rate in electropolishing is often overlooked because this process generally addressed for surface finish; however, it paramount on metallic sheet machining possessed with intricate geometry. Electropolishing removes material from the of a workpiece based anodic dissolution process. The depends current density, electrolyte, strength magnetic field, polishing time and temperature...

During the last few years, several sheet hydroforming processes have been introduced. Despite the advantages of these methods, they have some limitations. Of the processes, the two main ones are the standard hydroforming and hydromechanical deep drawing. A new sheet hydroforming die set was proposed that has the advantages of both processes and eliminates their limitations. In this method, a po...

Titanium alloys are extensively used in aerospace, missiles, rockets, naval ships, automotive, medical devices, and even the consumer electronics industry where a high strength to density ratio, lightweight, corrosion resistance, resistance temperatures important. The machining of these has always been challenging for manufacturers. This article investigates combined effect radial depth, cuttin...

Solder paste is the main soldering material used to form strong solder joints between printed circuit boards (PCB) and surface mount devices in the surface mount assembly (SMA). On average 60% of endof-line soldering defects can be attributed to inadequate performance of solder paste stencil printing. Recently, lead-free solder paste has been adopted by electronics manufacturers in compliance w...
