An experimental investigation of viscosity of a newly developed natural polymer-based media for abrasive flow machining (AFM) of 3D printed ABS parts

Abrasive Flow Machining (AFM) is the method of finishing complex surfaces and internal channels with help extrusion pressure abrasive-laden viscoelastic polymer media. This paper based on developing a new AFM media using natural waste as base material. In article, viz. rice husk ash-based has been developed, subsequently, rheological analysis done, experimentation performed Anton-paar® rheometer to optimize viscosity these newly developed this research study, hollow elliptical shape ABS (acrylonitrile-butadiene-styrene) material was manufactured FDM technique then finished one-way machine. examined parametric dependencies process parameters printed parts. The improved surface roughness parts investigated relating parameters. maximum achieved by 95.98%.
