The process for reducing the weight of the structure is chiefly performed by the machine processing. But, increasing the weight for strength of welding zone and geometrical defect are occurred in machine processing. In this study, chemical milling is applied to reduce the weight of the cylinder. Before chemical milling is applied to the cylinder, specimen testing is performed. After the specimen testing, NaOH 15% is selected to perform the chemical milling. After the chemical milling, the velocity of reagent is 0.0016 mm/min and the thickness of cylinder is about 2.4 mm after chemical milling.

Chemical machining(CHM) is a special process which material removed by contact of strong etchant. The application as industrial process was started from aircraft industry after 2nd world war. Chemical milling, one of the CHM process, initially became commercial bussiness and it was called chem-mill. Even today, this process widely used to remove the material from aircraft wings and fuselage panel in aircraft industry. In this study, it is attempted to design the cylinder pattern which minimize the weight within the allowable stress using chemical milling.
