correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

Abstract The influence of micro-geometric irregularities on fatigue strength and, in particular, surface topography is widely accepted. different machining processes generate roughness machined parts that may significantly modify their behaviour and compromise use components where structural stability required. Therefore, the study these materials under cyclic loading stresses becomes highly re...

The research focuses on slurry abrasion and erosion of martensitic steels used in the mining agricultural industries. A traditionally constructed pot tester with corundum abrasives form was for wear characterisation. Wear testing performed each specimen 180 h. Every 20 h, pauses were taken to characterise size, weight, hardness, surface roughness. worn zone’s damage progression studied using op...

Rotary ultrasonic drilling (RUD) has become an effective approach for machining advanced composites which are widely using in the field of aeronautics. The cutting kinematics and corresponding material removal mechanisms distinct different areas during RUD. However, these fundamentals have not been fully considered existing studies. In this research, two forms interaction induced by vibration w...

The Ice abrasive water jet technology uses cryogenically cooled ice particles instead of the mineral used in Abrasive technology. aim is to avoid contamination workpieces with abrasives and reduce environmental impact this are sucked into a high-speed speeds up 600 mxs-1 using Venturi effect. Direct observation process very difficult due extreme operating conditions. We have clearly shown that ...

Abstract In recent years, 3D printing technology is often used in various fields such as industry, medical care, and academia, because it can produce components with complex shapes at a lower cost than traditional processing. However, the size of products limited by printable range equipment, so large objects need to be disassembled printed before joining. Friction stir welding join different t...

The harvesting and implanting of bone graft is a complicated expensive orthopaedic procedure. This study introduces unique designed hollow drill bit novel technique rotary ultrasonic drilling porcine to get precise hole for screw insertion can harvest cortical with the least debris generation. new diamond impregnated compared conventional surgical without providing vibrations. Also, variation i...

Abstract In this work, we present a fully atomistic approach to modeling finishing process with the goal shed light on aspects of work piece development microscopic scale, which are difficult or even impossible observe in experiments, but highly relevant for resulting material behavior. large-scale simulative parametric study, varied four most grinding parameters: The material, abrasive shape, ...
