As the Mobile and Display technology are being developed quickly, new wireless devices are released in great numbers. They reduce existing devices' life time and demand a reduction of developing period of portable devices. With these demands, existing film cutting mold used many films of portable devices, especially LCD Display, needs to be more precise, and cheaper.
In this research, machining characteristic of SUS420 sheet that have good hardness, corrosion resistance and ablation resistance was analyzed through basic experiment using ball end-mill. And blade status of flexible cutting die fabricated with unique mechanical machining and blade status of die fabricated with cutting tool including chemical etching were compared and proper manufacturing process was intended in flexible cutting die.
