In this Research, the frequency forming method is suggested to micro pattern forming on the metal substrate and the optimal frequency can be manufactured micro pattern on the metal substrate is researched using an experimental method. So many researchers study about micro forming technology such as micro deep drawing, press forming, forging, extrusion etc. But if we want to make a micro pattern on the surface of metal substrate, we must use multi-step forming process to maintain the size of product or substrate. The frequency forming method can be used to solve this problem because the frequency forming method makes the surface to be a vibration mode status and easily deform the surface profile of mold. This paper describes the frequency forming system and optimal frequency range to make a micro pattern on the metal substrate (Cu materials). The frequency range can be classified to high frequency, super sonic range, and low frequency range.

FDB formation methods the material which sinters in the form there is a method electro-polishing. But this case is deffect of the corrosion or the material occurs with effect of polishing misfortune and the case where the product value fails occurs. This paper is, first the material which sinters press to use a secondary pattern-die the productivity and work speed improve with the method. The formation condition in the material the assault decides the formation load which falls in standard and until 800㎏f-1500㎏f it divides and a formation characteristic it compares. As a result of showing to get near to the recording standard where the load will increase.
