Abstract
This research aimed to identify the effect of punch speed and tool blanking material on the quality of the sheared edge bone-implant product in the form of a keychain cranioplasty plate implant. This research used Ti-6AL-4V sheet metal, 2.5% clearance between punch-die, various punch speeds, and materials of tool blanking. The tool blanking material used the standardized equipment for the blanking process. The sheared edge characteristic with the swift punch and high elastic modulus improved the shear zone 75% more of the workpiece thickness. The utilization of 71.76 mm/s speed and AISI M2 material created a smoother sheared edge of keychain cranioplasty plate compared to the others.
