Inconel 718 superalloy is widely used in aerospace industries for fabrication of the various components aircraft engine because its high strength at elevated temperature. It an extremely difficult-to-machine material due to work hardening nature and poor thermal conductivity. Creating micro-holes precision this beyond capability conventional twist drill low Micro-electrical discharge machining (micro-EDM) a well-established process any electrically conductive hard brittle material, but very...
Polymer nanocomposites (PNCs) have recently grown in material research because of their dominant applications and strength compared to counterparts.In this study, Silicon Dioxide (SiO 2 )-Epoxy Nanocomposite (SENC) with 1 %, 3% nano-silica fillers by weight reinforced epoxy 0.5 % Graphene Epoxy (GENC) is made solution casting method.The specimens were tested for flexural strength.The comparative plots stress-strain force-extension are drawn neat along SENC, GENC.It observed that SENC shows...
High energy input of grinding that is dissipated as heat in zone leads to thermal damage the workpiece material. Heat transfer phenomena during deep cut general and creep feed particular entirely different than shallow processes. Therefore, investigation temperature distribution becomes important such situations. In present work, a two dimensional thermal-based finite element model has been developed investigate transient within contact well whole due surface grinding. After comparing...
Inconel 718 superalloy is an extremely difficult-to-machine aerospace material due to its work hardening nature and poor thermal conductivity. Drilling of cooling holes in this much difficult by conventional drilling processes because it has high chemical affinity with cutting tool materials, welding action chips at rake face, strength temperature nature. In consideration all these problems, a self-developed setup ultrasonic assisted micro-EDM (drilling-UA-micro-EDM) been used create...
The study of grinding contact zone temperature and distribution in the workpiece during high efficiency deep surface (HEDSG) is important for quality product wheel wear. As a consequence temperatures present HEDSG, not only wear increases, but large residual stresses may also develop resulting cracks. Even microstructural changes occur if sufficiently large. work aims to two-dimensional (2D) thermal finite element method (FEM) model simulation as well whole HEDSG. has been used calculation...
The development of an accurate model for the prediction surface roughness is still a key issue Micro Electro-Discharge Machining (micro-EDM) due to its complex nature. In this paper, Finite Element Method (FEM) based thermal developed estimate on geometry crater produced during micro-EDM process. obtained using temperature field in workpiece. More real considerations such as Gaussian heat flux distribution, dependent material properties, phase change phenomena and overlapping craters are...
Titanium alloys are highly demanding in aerospace industries due to its high strength-to-weight ratio and hot hardness, termed as difficult-to-machine materials. Creating microholes of accuracy these materials is challenging task for manufacturing industries. Conventional twist drills generally failed the micromachining low thermal conductivity alloys. In consideration all problems, authors used self-developed hole-sinking micro-EDM (HS-MEDM) setup without with assistance ultrasonic...
High amount of energy generated during creep-feed surface grinding is dissipated as heat in zone. Due to high and uneven temperature, thermal stresses are the workpiece. Thermal can lead micro-cracks, decrease strength fatigue life components. Therefore, investigation stress distribution workpiece becomes important such situations.
