Abstract

In this study, an experimental study was carried out to the investigation on punching process of the circular hole on commercially pure titanium sheet by a hydraulic punch machine. Sheared face geometry and hardness distribution resulted from punching process were investigated. The commercially pure titanium sheet with 0.4, 0.5 and 0.6 mm thickness were used in the experiment. The diameter of the punch is 1.7 mm and clearance of punch-die is 7.5%. In the experiment, punch speeds used were 1 and 6.5 mm/s. The results show that punching process on the CP-Ti sheet can increase surface hardness, however hardness distribution on the punched hole are uneven. Hardness distribution on punched hole shows as getting closer with a sheared edge, the surface hardness is bigger. Punch velocity and material thickness increases, burnish height increases, while fracture height decreases.
