An Effect on the Process Parameter of Mg Alloy at Warm Sheet Forming

Mg 합금 온간 판재 성형시 공정 변수의 영향에 관한 연구

Since the sheet metal forming of Mg alloy is performing at elevated temperature, the effect of process conditions related with the forming temperature is very important factor. Therefore, the investigation for process variables is necessary to design the tools and process conditions. In this study, the effects of process variables were studied by the experimental and FE analysis using the square cup deep drawing. The temperature, forming speed, and lubricant condition were investigated. When forming temperature was $250^{\circ}C$, speed forming was low, and teflon sheet was used as lubricant, the formed parts were good without defects.
