Process Planning System for CIM in Shipbuilding

An initial hull structural modeling system for computer-aided process planning in shipbuilding

At the initial stage of ship design, it is difficult for designers to define all design information of a hull structure on 2D drawings. Thus, other designers must undertake the arduous task of translating such information to generate a 3D CAD model of the hull structure which is required at the following design stage such as the initial process planning stage. Since this task needs much time an...

Virtual CIM System: A Reality in CIM Training

Virtual Reality (VR) technologies have transformed the landscape of intelligent computer based instruction and offer unique new viewpoints on the core goals of education and training. What distinguishes VR from all preceding technology is the sense of immediacy and control created by the immersion process: the feeling of “being there”. Over the last ten years, Singapore manufacturing industries...

Semi-generative System for Manufacturing Process Planning

The generative method is a subject of theoretical and experimental research. Difficulties with its implementation are connected with the lack of formal description of the synthesis of activities constituting the manufacturing process. To overcome the difficulties while developing the huge technological knowledge base, a semigenerative method is often used. In this method the pattern is characte...

A system for case-based process planning

A new approach to automated process planning, integrating generative and case-based planning methods, is presented. Unlike most of the existing Artificial Intelligence (AI) based process planning systems, this approach makes use of a dynamic knowledge base containing old cases, i.e. part descriptions and corresponding process plans. This knowledge base grows with experience and therefore may re...
