the electro discharge machining (edm), one of the methods used in the machining industry and a non-traditional manufacturing method, the electro erosion process does not depend on the hardness of material and offers a way to process materials of very complex geometry with very fine and high precision by using cheap electrode materials, which make it a preferred method. in this study, effect of ...
This paper focuses on wire electrical discharge machining (WEDM) of devices made from commercially available sintered neodymium-iron-boron (NdFeB) rare-earth magnets that have been magnetized before machining. We conduct an experimental study to quantify the effects of the voltage and capacitance of an RC-type WEDM machine, as well as the magnet polarity, on slicing rate, mean kerf, and variati...
Shape memory alloys are kind of smart materials, which have distinctive properties and are superior in compare with other alloys. Severe reactions to thermodynamic and mechanical parameters and ability to return to their original shape make these alloys distinctive from other alloy regarding machining ability. Since these alloys have a very useful application in various fields such as aerospace...
Inspired by the array microstructure of natural superhydrophobic surfaces (lotus leaf and cicada wing), an array microstructure was successfully constructed by high speed wire electrical discharge machining (HS-WEDM) on the surfaces of a 7075 aluminum alloy without any chemical treatment. The artificial surfaces had a high apparent contact angle of 153° ± 1° with a contact angle hysteresis less...
High carbon high chromium alloy tool steels (D-3) with excellent abrasion resistance (HRC: 58-65) are increasingly used in manufacturing high performance cutting tools (dies and punches), blanking and punching tools, extrusion tools, etc. Being a hard material, it is difficult to machine using conventional machining methods. Wire Electric Discharge Machine(WEDM) seems to be a viable option to m...
In this paper, an experiment is conducted to optimize the kerf width of wire electrical discharge machining (WEDM) on Aluminum hybrid composite with Zinc coated brass wire using Taguchi method. Aluminum metal matrix composites (MMCs) reinforced with silicon carbide particulate (SiCp) find several applications due to their improved mechanical properties for a wide variety of aerospace and automo...
Wire-EDM is a highly complex machining process, which is characterized by non-linear behavior. Owing to unique capabilities of machining complex shapes and hard materials with high accuracy and fine surface finish, WEDM is used in various manufacturing industries. There has been on-going research to develop automated capabilities for WEDM by understanding the interaction mechanism of various in...
Advances in micromachining techniques have led to the evolution of micro-electromechanical systems (MEMS). These techniques are typically based on semiconductor manufacturing processes, which offer various advantages such as batch manufacturing of miniaturized devices and monolithic integration of microelectronics with the devices. Surface micromachining has been used to construct complex micro...
Abstract Micro slots and textures are created on Titanium (Ti) composites to improve its surface characteristics. Micro-textured Ti generally recommended for bio implants, automobile, aerospace components. In the current research, Ti-B 4 C nanocomposites were prepared by powder metallurgical route. cut surfaces Wire Electrical Discharge Machining (WEDM) Technology varying current, pulse-ON time...
A new strategy with bone tissue engineering by mesenchymal stem cell transplantation on titanium implant has been dawn attention. The surface scaffold properties of titanium surface play an important role in bone regenerative potential of cells. The surface topography and chemistry are postulated to be two major factors increasing the scaffold properties of titanium implants. This study aimed t...
