The purpose of the present. paper are not to develope machine tools of new concepts and advanced mechanisms but to introduce and apply new methods and concepts in the design procedure by using and changing the previously existing technologies. In this paper 3D modeller was proposed for designing machine tools and the design automation software(DesignMecha 2000) was used. 3D modeller enabled more fast design and the better manufacturability checking than 2D one so that design error was dramatically reduced. As designer may easily understand the real shape of a part and assembly object, it's easy to draw the drawings not only in a conceptual design but also in a detailed design. Also, design automation software enabled designer to consider the real important design parameters by reducing time to spend in estimating and calculating the strength of the model by the computer aided automatic calculation instead of a tedious and complex: calculation by manual method and help him to easily make the decision for selecting the stocks and design the structure of part or unit of machine tools.
Generally, the edge preparation of the ship water ballast tank inside is worked with just one pass grinding. According to the SSP(Secondary Surface Preparation) rule, the edge preparation must keep 2R or 3-pass grinding. The collar plate edge grinding of the ship inside is manually progressed by worker. In addition, the poor working condition cause grinding workers to avoid working in them, and the quality is determined by the skill-level of a worker. So, this research, successfully focused on overcoming the difficulties in working condition and development of automated grinding machine for standard collar plates.
