Abstract
With the constant development of industrial technology, precision processing systems are required to be diversified, accelerated, and enlarged. Consequently, interest in machine tools for the high-speed processing of large workpieces is increasing. automatic tool changer (ATC) is an automatic tool change device for automatically changing tools during work and is important part of the machining center. The ring-type automatic tool exchange device is advantageous in terms of the number of tools and the size of the magazine owing to its faster operating time and higher space efficiency than before, and ability to use large-sized tools. In this study, seven cases improved according to the thickness of the ring magazine selected using finite element analysis (FEA), and the optimal design was evaluated by static structural and dynamic analysis and multibody dynamics analysis for each case.
