Research ArticleOpen accessPhrase in the titleThe Effect of Corner Radii and Part Orientation on Stress Distribution of Cold Forging DieAhmad Baharuddin Abdullah, Kam Shwu Ling, Zahurin SamadOne of the most critical problems in cold forging is the huge stresses generated from the deformation of metal leads to die failure. The distribution of stresses mainly depends on geometry of the die. An approach to optimal design in cold forging die geometry and orientation are presented in this paper. The impression cold forging dies of the Universal joint … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,340 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsTwist Springback Measurement of Autonomous Underwater Vehicle Propeller Blade Based on Profile DeviationAhmad Baharuddin Abdullah, Mohd Sapuan Salit, Zahurin Samad et al.Geometrical defects that are attributable to springback are among the major defects induced by the sheet metal forming process. Such defects are critical for sections with varying thickness, such as Autonomous Underwater Vehicle (AUV) propeller blades. In this study, the springback in the twist-bending of an AA6061 propeller blade was quantified by comparing the targeted and manufactured profiles obtained using … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 31 May 2013 · 7,383 accessesView PDF Cite

Research ArticleOpen accessIn the abstractClosed Die Forging Geometrical Parameters Optimization for Al-MMCM. Jolgaf, S.B. Sulaiman, M.K.A Ariffin, A.A. FaiezaDemand for lighter and stiffer products has been increasing in the last few years especially in automobile manufacturing. The closed die forging process of Metal Matrix Material (MMC) is presented as possible solution, since it produces parts with good mechanical properties and lighter weight. A computational modeling of closed die forging process using finite element method and optimization techniques makes … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 8,482 accessesView PDF Cite
