In metal forming, coefficient of friction plays a vital role in plastic forming of material. Mechanical properties also influence the forming processes. Further, Frictional coefficient affects the microstructure of finished material, tool wear and decides the amount of energy needed for forming. This study enables to compute the adhesion friction factor during plastic forming. Usually, Standardized specimen dimensions (6:3:2), derived from Plasticine model of has followed for experimental studies. The ring compression test takes into account the percent change in inner diameter to the percent change in height. Experimentation was carried on 316L (N) specimens of dimension (12:6:4) mm at dry conditions in temperatures ranging 900, 1000, 1100, 1200°C. After the ring compression, the final dimensions were calculated by Vernier caliper and LEXT 3D laser confocal microscope to compare the results effectively. Validation was carried out in ABAQUS software.
