Surface quality is the most crucial factor affecting product lifespan and performance of any component. Most earlier technologies display accuracy in micrometre or submicrometre range, surface roughness nanometre almost no defects production optical, mechanical electronic parts. Such finishing methods incorporate a magnetic field to control forces using magnetorheological fluid as polishing medium. Magnetorheological (MR) consists ferromagnetic abrasive particles. It type modern intelligent...
Fused silica glass, in particular, offers a broad range of applications optics. The present study investigates fused samples using non-conventional medium-pressure plasma polishing at optimum machining parameters. parameters, i.e. gas composition (He: (SF6+O2)) 90:10, pressure ratio (SF6:O2) 1:1, total chamber 5 mbar, and radio-frequency (RF) power 80 W have been obtained parametric conditions. highest material removal rate 100.36 × 10−3 mm3/min is achieved optimized process Even though the...
In order to achieve a process for precision asphere and freeform surfaces, medium-pressure plasma (MPPP) is developed high-rate machining of optical materials. Fused silica commonly used fabricate components such as mirrors, lenses, prisms, photonic crystals. Plasma polishing, an unconventional method, employed the atomic-level removal material from substrate’s surface. While polishing fused substrate, focus lies on investigating parameters, specifically radio frequency (RF) power, sulfur...
The plasma polishing process is one of the non-conventional techniques used to remove material at atomic level from substrate. During fused silica substrate, parameters, namely radio-frequency (RF) power, pressure ratio (SF6/O2), and total chamber, are investigated optimised for removal rate (MRR) % change in surface roughness (% ΔRa) using response methodology. optimum values obtained MRR ΔRa 0.012 mm3/min 3.59, RF power 60 W, 3, 14.3 mbar. experimental results reveal that slightly...

The geometric intricacy of tiny gears makes nano-finishing difficult. In the current study, magnetorheological (MR) polishing process is used for intricate surfaces gear components uniformly. For polishing, technique employs a dynamic fluid recognized as (MRPF), that has ability to stiffen in presence magnetic field. Base media, iron and abrasive particles are utilized synthesize MRPF. Permanent magnets produce necessary field finishing zone. Finite element analysis (FEA) model understand...
This article focuses on the morphology, shape, and size of NPs which are crucial steps in nanotechnology. The production tungsten carbide (WC) nanoparticles tool wear rate under different voltage duty factors have been studied two dielectrics, i.e., EDM oil kerosene. It has seen that generation increases with an increase at a constant factor. maximum amount generated was obtained factor 20%, 40 V 0.1013 gm 0.0447 kerosene, respectively. higher value observed 0.000278 gm/min 0.000192 is more,...
