Experimental and theoretical investigation into surface roughness and residual stress using ball end magnetorheological finishing

Performance Evaluation of Improved Ball End Magnetorheological Finishing Process

A novel nanofinishing process using improved ball end magnetorheological (MR) finishing tool was developed for finishing of flat as well as 3D surfaces of ferromagnetic and non ferromagnetic workpieces. In this process a magnetically controlled ball end of smart MR polishing fluid is generated at the tip surface of the tool which is used as a finishing medium and it is guided to follow the surf...

an investigation into translation of cultural concepts by beginner and advance student using think – aloud protocols

this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...

Experimental and theoretical investigation of magnetorheological elastomers with layered mesostructures

Magnetorheological elastomer (MRE) is a type of smart material which can vary its shear modulus rapidly, continuously and reversibly, by the external magnetic fi eld. MRE has attracted increasing attention and been widely used in various applications. Generally it has been created by dispersing magnetic fi ller particles in polymer matrices. Most current studies are focusing on the microstructu...

Theoretical and Experimental Investigation into the Adhesion between Fiber-Reinforced Bitumen and Aggregates by Using Pull-out Method

An Experimental Investigation on Surface Roughness and Edge Chipping in Micro Ultrasonic Machining

Surface quality including surface roughness and edge chipping is a key process measure in micro ultrasonic machining (Micro-USM) as an efficient process for micromachining of hard and brittle materials. Process parameters such as ultrasonic vibration amplitude, static load, type of tool material, type and size of abrasive particles and slurry concentration can influence the surface quality. How...
