Performance Measurement in Incremental Deformation of Brass Cu67Zn33 Through Soft Computing Tool

摘要

Incremental deformation is an innovative manufacturing process. Commonly, it is known as incremental sheet forming (ISF). The deformation of sheet to a single point tool therefore it is called the single-point incremental forming (SPIF). The surface finish is the common issue in SPIF which is increased with the processing of hard materials. In the present study, the brass Cu67Zn33 is formed through SPIF, and nano-scale surface roughness is measured through atomic force microscopy (AFM). A soft computing tool, i.e., artificial neural network (ANN), a second-order mathematical prediction model, is established due to variability in experimental outputs. The SPIF is successfully done on brass Cu67Zn33, and the error found in predicted R_a is in the range of -6.813-73.04.
