| Research Abstract |
This research aims development of dry and precision punching process utilizing rapid Diamond-like carbon(DLC) coating. DLC coating was performed at atmospheric pressure by nano-pulse plasma chemical vapor deposition method. DLC films deposited contain less than 27 atm.% of hydrogen and exhibits larger than 10 GPa in nano-indentation hardness. Coating process was applied to punching process and we found that punching force was stabilized by DLC coatings because DLC coating prevent from adhesion of aluminum work piece on punch surface.
