“…These are influenced by cutting force, depth of penetration and particles size and type. Many researchers have made an attempt to develop different variants of AFF technique for finishing various internal and external cavities like microchannels, micro bores [18], rotors and turbine blades [19], spring collect [20], nozzles [21][22][23], gears [24], injection mold [25], knee and hip implants [26,27]. Also, many components used in micro-electro-mechanical systems (MEMS), industry and biomedical are finished to the required level of accuracy which cannot be met by conventional methods.…”

Unidirectional abrasive flow finishing process was used to finish stainless steel SS316L and titanium alloy Ti-6Al-4V materials which are widely used as implant materials. Viscoelastic polymer-based flexible abrasive media was used to finish these surfaces with different pressure and number of cycles. The obtained surface roughness and surface topography were measured using profilometer, and morphology of the surface was studied using a scanning electron microscope. Further, the wettability of the finished surface was studied by measuring the contact angle (θ) for three liquids-water, formamide, and diiodomethane using the sessile drop technique. The measured contact angles were used to ascertain the surface free energy components using Van Oss Chaudhury-Good equation. Significant difference was observed on surface roughness, contact angle, and surface energy of the machined surfaces at different finishing cycles. Also, the different tendencies of the droplet contact angle and surface energy have been observed along the direction parallel and perpendicular to the finishing direction and it gave a strong conclusion that surface roughness and surface textures play a significant role in wetting characteristics. So, this work provides an overview of the interaction between droplet and surface topography of finished SS316L and Ti-6Al-4V surfaces. Further, an empirical model has been developed using the response surface methodology (RSM) for output responses namely, average surface roughness (R a ) and material removed (MR). Interactive effects of number of cycles and pressure on average surface roughness and material removed are discussed in this paper.

“…16,17 Some researchers used AFF to finish different types of gears focusing on reduction of their surface roughness only. Xu et al 18 used AFF for finishing helical gears and reported significant reduction in surface roughness of flank surfaces of gears with high processing efficiency. Venkatesh et al 19 used AFF for finishing straight bevel gears made of EN-8 steel and found 50% reduction in surface roughness.…”

This paper reports on reduction of noise and vibrations of cylindrical and conical gears through simultaneous reduction in their microgeometry errors, functional parameters, and surface roughness by finishing them with abrasive flow finishing (AFF) process. Previously identified optimum values of AFF medium viscosity and finishing time were used during AFF of the chosen gears. Noise and vibrations characteristics of the unfinished gears and the AFF finished gears were studied by varying motor speed and applied load at four levels each. An indigenously developed test rig was used for spur and straight bevel gears whereas drivetrain diagnostic simulator was used for helical gears. Indigenously developed dual flank roll tester was used to evaluate functional parameters of the unfinished and the best finished gears by AFF process. It was found that AFF process simultaneously reduced microgeometry errors, functional parameters, maximum and average values of surface roughness of spur, helical, and straight bevel gears. It reduced noise and vibration by 5.2 dBA and 5.3 m/s2 for spur gears, by 3.4 dBA and 7.5 m/s2 for helical gears, and by 4.6 dBA and 4 m/s2 for straight bevel gears. This study proves that AFF is an easy-to-operate and effective process for reducing noise and vibrations of cylindrical and conical gears through simultaneous reduction in their microgeometry errors, functional parameters, and surface roughness values. Outcome of this work will be helpful for various manufactures and users of different types of gears.
