The knitwear industry requires ways to satisfy a changing environment. This study suggests a knitwear design process using a knit CAD program. Such a process needs to implement a CAD system that develops a sufficient knit design system to advance the knitwear industry in both planning and manufacturing. In order to contextualize this research, this study reviewed the current state and problems of the knitwear industry and the market, and investigated the actual condition in which the CAD system is used in knit design by CAD system service providers. The findings of the study are as follows: First, All brands had individual ways to reduce the amount of lead-time. The knit designers pointed out that any given sample product is made in the form of a swatch; after the knitting step and prior to the manufacturing process. In women's wear brands, basting was inserted into the production process in order to reduce the amount of sample losses. Second, a CAD program enables the uses of swatches to see the adequacy of yams, textures, and style that simulate the completed style. Third, this study examined the efficiency of knit design process conducted by the knit design CAD system based on expert assessments, showing that the use of a knit CAD program in commercial knit design proved to be more efficient than in previous models.

The purpose of this study was to utilize of the CAD system in pattern making process for women's bodice sloper, especially in education of the drafting. Accumark 540 System was used for this study. The drafting program was developed by the use of macro program in CAD system. The results from this study : 1. The Lim Won Ja's system of bodice sloper was selected in this study. The hand drafting of the system was arranged developing the macro program of bodice sloper. 2. The program consists of eight subprograms I sequence of the drafting order. In running this developed program, proper figure is drafted by inputing data. And the drafting process is automatically presented in interactive mode. 3. It has been developed to input the function of French Curve Ruler to increase the effectiveness of curved line treatment. The program can also be used in the curve part to present the manualy sensible function. 4. In case of education of drafting bodice sloper, the program provides the high accuracy, efficiency and a strong interest nterest in pattern making process by utilizing CAD system.

In this study surface modeling .method with 3D curve net is proposed. For surface modeling, ship hull was divided into several parts, Generated surface was loaded general purpose CAD program through IGES file format, and the quality of generated surface model was checked by CATIA's internal function. Lastly it is tried to find a method for improving the accuracy of surface connection by using the blending method in CATIA and the result was discussed.

Mass customization utilizes the new computer technologies, supply chain management, product information management, and some level of customization of the product for the individual customer. This study aimed at grasping the actual conditions of mass customization of domestic men's suit industry and the use of MTM CAD program. The MTM apparel production programs that are used by five leading men's suit manufacturers in Korea were compared. The results of the study showed that most of the manufacturers produced mass customized men's suits to supply extraordinarily large or small size suit based on the individual order. The information listed on an order sheet used at shops was not necessarily corresponding to the information in the MTM CAD program that is use for production of suit ordered from the shop. The pattern data base on the MTM CAD program are constructed based on the sizing system of individual manufacturer. The most manufacturers translated the customer's body dimensions into difference between the standard pattern and the customer's needed adjustment.

Recently, the fashion industry has been integrating with The IT industry in order to develop in various ways. This study looks into ways to utilize the 3D CAD system, which would reduce time and cost while producing samples, and strengthen the communication between the brand and its cooperators by deploying knit designs using Knit CAD system's 3D virtual clothing program. The research method was reference, Internet resources 3D fashion CAD system and 3D Knit CAD system. Based on the data, simulation of the complete design of 4 deployed knit designs was done by using 3D virtual clothing program of the Knit CAD system utilizing knit design elements. One of each design element among the virtual clothing designs was chosen to produce real clothing, and the experts did verification on the appearance assessment of 3D virtual clothing knit designs of the Knit CAD system. As a result, 3D virtual clothing knit design of the Knit CAD system proved itself as an efficient system in terms of time and cost.

The objectives of this study is to create an environment which students could apply effectively through focused on the innovative methods of education and CAD course contents. The facts which were able to figure out from this study were as follows ; 1. After the analysis of the CAD course contents of the american universities, their common contents were in order of introduce to Computer Aided Drafting and design with Auto CAD/ provide fundamental knowledge of the application for use in design/ examine and how this effects 2 D image and model creation/ CAD as a design tool . Over all trend of CAD course contents of interior design program in american university is moving toward utilizing CAD as a design tool. 2. On the other hand, common contents of our local universities were simply introducing CAD. It means that our course contents are more methodological and theoreatical . And american university's program is focused on problem solving solution as a design tool.

In this study, a robot welding programming system is developed for gantry-type robot using a neutral CAD data format. The system automatically extracts welding line data from tile CAD model represented in IGES format and generates a robot program based on the weld line extracted. The welding program is simulated jar verification by using IGRlP, a virtual manufacturing solution. The robot welding programming system is demonstrated with a simple example.

In this study we do for the thing to develop automatic geometry design program of a mechanical element that we have used in CAD/CAM system. The program, which produces automatically three-dimensional surface and a solid model that have been used in CAD/CAM system, widely create automated two and three-dimensional model to by inputting several necessaries for a design, fur the design element. It is emphasized if you are just a beginner having only basic knowledge of the mechanical engineering, you might be able to design easily a three-dimensional model. The software to be used to develop automatic geometry design program is visualLISP to be a developer program of AutoCAD.

In the recent years the computer-numerical controlled cutting process such as a plasma arc cutting and a laser cutting is widely applied to reduce the time and cost expense for generating NC part program of the parts to be cut. In the present study, a CAD system(C-CAD) was developed to generate automatically the NC part programs with CLDAT(Cutter Location Data)for the CNC plasma arc cutting system. The NC part programs are composed of the 2-dimensional drawing of the parts to be cut and the technological data. The shape data of the parts drawn in the Auto-CAD can be also used in the C-CAD, since the data file generated by the C-CAD is compatible with that by the Auto-CAD. In order to check its applicability, the C-CAD and CAM system were applied to cut the parts, and which showed the satisfactory results.

In order to improve in quality and productivity using the CNC machine tools, it has been endeavored to elevate production process by adding supplementary axes(2 axes) to 2,3 axial CNC machine tools. It is because the movement between the progress of work in processed goods is remarkably decreased more than that of general CNC machine tools that productivity improvement with precision maintenance can be improved. VBScript in CAD/CAM is applied to utilize CNC machine tools added supplementary axes so that Multi-axial &Multi-process manufacturin g program can be conveniently drawn up. However, there is generally much skilful work and operation by the manual program of CAD(2.5D) and CNC machine tools in the filed. As a result of conducting an experiment by COM-filing VBScript at the spot of Insert Tip for milling Face Cutter in CAD/CAM Software(2.5D), it was not only timesaving to draw up program but also more convenient than complicated Multi CAD/CAM Software to approach and possible to program various products instantaneously.
