Predicting maximum force in SPIF for different materials

Knowing the importance of predicting acting forces during formation process, our research has conducted 27 Single Point Incremental Forming (SPIF) experiments in hyperboloid format, followed by Finite Element Method (FEM) simulations and regression equations were determined to estimate maximum axial force process. ANOVA analysis variance was used determine significance material parameters response. A multiple linear model constructed SPIF After experiments, we able identify that increases according an increase tool radius, sheet initial thickness, strength coefficient values, as well decrease strain-hardening exponent. The FEM are agreement with experimental values found, proven be efficient describe results, R2 98.85% a percentage error 11.5%.
