Research Paper: Fine Finishing of Internal Surfaces using Cassava Starch Medium

• Share article :

This paper discusses the use of cassava starch, an eco-friendly and affordable material as a polishing medium that has the potential to revolutionize Abrasive Flow Machining (AFM) for impeccable internal surface finishes.

Key findings:
– Cassava starch is easily accessible and enables recycling without pollution.
– Concentration above 37% yields Shear Thickening Polishing Slurry (STP-s).
– Theoretical model (Archard sliding wear, fluid dynamics) shows 13.1% max error.
– Achieves low roughness (~20 nm Ra) in processing experiments.
– Temperature (>50 ℃) impacts processing efficiency; STP-s loses efficient finishing.

Pioneering the use of cassava starch marks a milestone in internal surface finishing, promising precision processing across techniques.
