Due to intense global competition, manufacturing companies need improve and optimize productivity, increase production flexibility, gain competitive advantages. Companies have begun look for new approaches strategies in the field of management. This includes tools like Single Minute Exchange Die (SMED) Total Productive Maintenance (TPM), which aim manage machines equipment, reduce waste lead ti...

In recent years, hydroforming process has been applied in different industries such as aerospace, automotive and military industries due to its advantages, such as high dimensional accuracy, capability of forming complicated parts and high drawing ratio. Hydrodynamic deep drawing with radial pressure is one type of hydroforming process. In this paper, forming of cylindrical cups in hydrodynamic...

    Below knee amputation, which is noticed as one of the most common lower extremity amputations, is caused as a result of various factors like trauma, disease, or congenital limb deficiencies. In order to take these amputees back to daily life, below knee prostheses are used as an alternate to original limb. Comfort and patients’ satisfaction with prostheses are directly related to each prost...

This paper attempts to investigate the influence of the microstructure and mechanical property changes on sand casting and permanent die casting alloys by grain refinement, modification combined action of both (Al– 3Ti–1B + Al–10Sr) and without grain refinement and modification effect. The microstructures of the castings are studied by optical microscopes. The microstructure and mechanical prop...
