This method is used to drill the holes ranging from macro to micro scale with good quality which are prime demand in electronics, automobile and many more industries. In this experimental work, SS 304 workpiece was drilled using copper and brass tool of 500 µm each. In order to investigate the effect of machine variables such as voltage, pulse on and pulse off time on material removal rate and taper cut, as per orthogonal array nine experiments were conducted for each tool. The results of both the tools were compared and found that at lower level copper tool performance was better and at higher levels brass tools performed well. The interaction effect of parameters were also studied for both the tools and concluded that there is no specific trend for interaction.

In this study, a comprehensive experimental investigation was conducted on the effects of shallow and deep precryogenic treatment with different holding times on the machinability performance of the 5083 aluminum (Al) alloy. For this purpose, shallow cryogenic treatment at -80 degrees C and deep cryogenic treatment at -196 degrees C were applied to the aluminum alloy for different time periods (15, 30 and 45 h). The performance outputs included tensile properties, thrust force, tool wear and surface topography. The highest tensile strength was observed in the sample kept in liquid nitrogen (N-2) for 45 h, while the effect of cryogenic treatment for 15 and 30 h on the mechanical properties of the other samples was observed to be limited. Moreover, cryogenic treatment increased the thrust force during the drilling operation; however, the treatment reduced the adhesion of the material to the drill bit and improved the surface quality. It can be concluded that cryogenic treatment has positive effects on the mechanical properties and machinability of the 5083 alloy. LA - English DB - MTMT ER - TY - CHAP AU - Rashef Mahbub, Md.

Although many of the current industrial applications of titanium alloys are at a larger scale, they can be used for microscale applications as well, especially where lightweight, and biocompatibility of titanium alloys are advantageous. Some of the important applications of microstructures made of titanium alloys are next-generation vascular stents, drug-eluting stents (DES), micro-opto-electromechanical systems (MOEMS), microfluidics, and bio-micro-electromechanical systems (bio-MEMS). In this book chapter, a comprehensive overview on micromachining of titanium alloys has been presented. The available literature on conventional, nonconventional, and hybrid micromachining of various titanium alloys has been covered in this book chapter. Starting on the methodology of the process in each case, the book chapter describes the effects of key machining parameters and performance criterions depending on previous works on those respective fields. In addition, micromachining challenges, such as burr formation, tool wear, property change of recast layer, improper surface finish, etc. have been addressed for each machining process and steps to overcome those issues have been suggested. Finally, a reflection on future research directions on the area of micromachining of titanium alloys has been included at the end of the chapter.
