This paper investigates the effects of tool holder materials on chatter vibration in turning operations. The study uses a complex dynamic model with two degrees freedom for orthogonal cutting system. Tool holders made from different materials, including Al 5083, 6082, 7012, and standard 4140 material, were subjected to investigate their process damping capabilities. found that allows higher sta...

The interface characteristics and microstructure formation of TA2-5083 composite plate after explosive welded were studied. Optical microscope electron used to analyze the intermetallic compounds. Furthermore, ANSYS/AUTODYN was adopted calculate simulated by smooth-particle hydrodynamics (SPH) method. results show that most molten metal in wave front stays wave-waist region. There a relative ve...

Coffee roasting is an important process in the coffee industry that determines quality of beverage obtained. The carried out a cylindrical tube having high temperature. Therefore, thermal stress on (drum) should be focused. In this paper, both appropriate materials selection and optimal dimension roaster drum are considered. Drum given load 200 o C 2 kg. Here, Aluminum Alloy 5083 Stainless Stee...
