An Internet-based system for setup planning in machining operations
Setup planning is a complex and intuitive process. An efficient setup planning system is essential to cut costs and to reduce lead-time. In this paper, an integrated system based on Internet for setup planning is presented. The system is implemented based on a simple three-tier thin client-fat server architecture. The utilizing of (extensible modeling language) XML as a file format provides means for the transfer of information between various manufacturing systems. A methodology for setup planning is also presented, and in which the machining precedence, tolerance requirement and fixturing constraints are taken into consideration. Hence, a practical and global optimal setup plan along with fixturing features in each setup will be generated by this methodology. A case study is presented to illustrate the proposed system and to show the effectiveness of the presented setup planning methodology.
The information management apparatus, a display form of an information presentation portion presenting explanatory information on the instruction information according to the type of the determination by the determining section and the determination section which determines a type of the indication information by the input unit and a control unit for controlling display. The description information, contains explanatory information on the art folder if and when the information designated by the input unit of an image in a folder, contains explanatory information on the art image, indicating a non-image within the input portion folders do. The information management apparatus, it is determined, display control, folders, images
