Recently, many studies have been undergoing to reduce working time in field of machine tool. There are two ways of reducing working time to reduce actual working time by heighten spindle speed and to reduce stand-by time by shortening tool exchange time. Auto tool changer belongs to latter case. Fixed address type auto tool changer can store more number of tools in small space than magazine transfer Ope and can shorten tool exchange time. This study focuses on the topology optimization to reduce the weight of the fixed address type ATC. The optimization program using a real number coding genetic algorithm is developed and is applied to the 10-bar truss optimization problem to verify the developed program. And, it is shown that the developed program gives better results than other methods. Finally, The developed program applied to optimize the fixed address type ATC.

This study is concerned about the design and structural analysis of high integrated tool tower ATC(Automatic Tool Changer) for machine tool. Recently, many studies have been undergoing to reduce a working time in a field of machine tool. Tool tower ATC belongs to reduce a stand-by time by shortening a tool exchanging time. The developed system can store more number of tool in small space than other machine. The analysis is carried out by CATIA V5 software. In the result of structural analysis, the safety factor of the developed system is confirmed.
