컵-컵형 축대칭 복합압출에 관한 실험적연구
An Experimental Study for the CUP-CUP Axisymmetric Combined Extrusion
초록
Effect of some process variables including area reduction, stroke advance, materials on the extrusion load, plastic flow and height ratio of upper to lower extruded parts in the cup-cup axisymmetric extrusion were experimentally investigated and analyzed. Deformed pattern is visualized by grid-marking technique using half-cut billets splitted. The influence of using split specimen and original specimen on the extrusion load and height ratio is examined by experiment.
