Experimental Investigations of Nano Finishing Process on Nickel-Free Austenitic Stainless Steel by Grey Relational and Principal Component Analysis

The nano surface roughness of metallic materials is important in engineering and medical fields for specific applications. Magneto rheological abrasive flow finishing (MRAFF) process was performed on nickel-free austenitic stainless workpieces order to obtain at the level also forecast performance MRAFF terms responses such as (SR) material removal rate (MRR). These two are affected by factors hydraulic pressure, current electromagnet, number cycles during machining process. design experiments (DOE) used determine contributions parameters output responses. techniques grey relational analysis (GRA) principal component (PCA) were these experimental investigations discover that minimise final Ra maximise MRR. Through DOE, a minimum SR 63.24 nm maximum MRR 2.34 mg/sec obtained samples combination 30 bar 6 A current, 300 cycles.
