Abstract
Due to the ever-advancing technology in various production industries, the materials of machined products have been diversified from simple steel materials to composite materials, powder metallurgy materials and silicon. Powder metallurgy materials have excellent mechanical/chemical properties, but have disadvantages such as; difficulty in processing using conventional processing methods, increased processing cost and generation of a large amount of dust. In addition, the need for the development of specialized machine tools increases due to the disadvantages such as the frequent occurrence of burrs in tapping and drilling. In order to solve the problem of machining of high hardness sintered products, a method of maximizing productivity and efficiency by processing the powder metallurgy material before it is completely sintered is being studied. In this study, structural analysis of a turret center for the verification of structural stability of a turret center for processing powder metallurgy materials was carried out. In addition, the shape was optimized to improve the structural stability and weight and presented an optimal model. The study aimed at developing more reliable turret center through the optimized model.
