This study has analyzed the impact of the characteristics of groove angle, ampere, and voltage density of welded material, which are the FCAW welding requisites, to the welding process. In addition, it is going to present the optimum post heat treatment conditions compatible to the vessel classification rules through the impact analysis of heat treatment to the mechanical characteristics of welding area with the comparative analysis of mechanical characteristics of welding area before and after heat treatment.

Among drilling operation, the most difficult machining method is deep hole drilling. And deep hole drilling is difficult by using conventional drilling operation because it has problems such as chip removal, cooling and lubrication for the cutting tip and vibration problem and strength requirement of the tool. To solve these problems, the most adequate drilling method is to use tool which can supply high pressure cutting fluid. And the typical method for this application is the BTA drill. This study is related to the fuel oil supply pipe for the large ship and machining of it.

Current needs' and preferences of consumers to meet a variety of small quantity batch production is being made. Thus the period from development to production of products is shorter. Shortens the product life cycle,. especially the prototype period is shorter. To address these requirements, rapid prototyping is being used. In this study, We will propose how to create spur and helical gears and how to use them with automatic design program developed by using VisualLISP.
