축대칭 압출에서의 유동경로를 이용한 실용적 금형설계
A Practical Method to Determine the Die Shape using a Streamline in Axisymmetric Extrusion
초록
A new simple method to determined the die shape using a streamline in extrusion is presented. This method assumes that a billet deforms naturally to minimize the energy input for the given process condition. Then an optimal die shape can be determined along a streamline. Extrusion operations with two types of materials strain-hardening material and strain-rate hardening material are examined using this method. Prediction with the proposed method are compared with those by the previous optimizing model to show its efficiency.
