Collaborative Process Planning

Computer Supported Cooperative Work (CSCW) has been considered as a promising approach for developing process planning systems and optimizing process plans. Process planning based on CSCW is inevitable for reducing manufacturing preparation time and costs through concurrent and collaborative engineering. Since process planning is a huge and complex job, several process planners should execute planning together. Therefore, information exchange in collaborative process planning is very frequent and the synchronization for each user has a decisive influence in collaborative process planning system. In this research, expression of process documents based on XML is studied and the method that process documents are mapped into XML documents is described. Implementation of synchronous mechanism is presented to develop the system of collaborative process planning.

Collaborative Process Planning

To ensure competitiveness in today’s market, process planning should be collaboratively performed in manufacturing enterprises. Since process planning is a huge and complex job, several designers should process planning together. Designers consult with one another regarding the results through continuous communication and collaboration. In this research, key technologies are studied according to requirements analysis on collaborative process planning system. The flow is described based on the characters of collaborative process planning. The structure of this system is built and the system is implemented to save the cost and improve the reliability of process planning.

Collaborative Process Planning

Computer Supported Cooperative Work (CSCW) has been considered as a promising approach for developing process planning systems and optimizing process plans. Process planning plays an important role in the computer integrated manufacturing environment. Process planning based on CSCW is inevitable for reducing manufacturing preparation time and costs through concurrent and collaborative engineering. In this research, two key technologies of data exchange method and data communication method are studied based on the analysis of structure and business flow for collaborative process planning. The collaborative process planning system has been developed and adopted to support collaboratively work.

Abstract An intelligent case-based process planning system with interactive graphic simulation environment, PROCASE, is developed to demonstrate an integrated methodology of case-based process planning system. In PROCASE, both the mechanical part features and the machining operations are represented with a frame based scheme. PROCASE contains a retriever, a modifier, a simulator and a repairer. It distinguishes itself from traditional rule-based process planning systems by representing the process planning knowledge through previous process planning cases instead of production rules. It therefore can overcome some problems in the traditional rule-based expert systems. PROCASE currently resides in IRIS Indigo workstation. With a user friendly graphic environment, the generated process plans can be demonstrated vividly. This simulation environment not only serves as a good assistance in debugging, but also helps the user to be convinced of the outcomes of the reasoning of PROCASE.

Machining Process Planning

An automated machining process planning system for rotational parts is designed, developed and implemented. The system is called IPPS_R for Intelligent Process Planning System for Rotational parts. The IPPS_R system is designed for generating process plans for manufacturing rotational parts using metal cutting operations. A generative approach is employed to determine process operations and sequences automatically. For each machining feature, based on the accuracy and surface quality requirements, a fuzzy logic approach is developed to generate machining operations. A method of ranking the machining priorities of the features according to the feature relationship matrix is developed for sequencing operations. Moreover, the heuristic search of process plans is achieved by minimizing the number of setups in a plan. Finally, the IPPS_R system with a user-friendly interface is implemented in Microsoft Visual C++ on a personal computer, utilizing Microsoft Foundation Class (MFC). Two sample parts are used to demonstrate applications of the IPPS_R system.

Abstract Agile manufacturing combines the strengths of qualified partners in a virtual organization to meet a certain market need. High level process planning is a way to aid designers to improve their design with respect to the capabilities of potential partners. An automated high level process planning system for mechanical components has been developed which considers both global and partner-specific manufacturing capabilities so that cost, cycle time, and quality attributes can be derived for a given design. The system generates a set of manufacturing operations and candidate partner plants that can contribute to the manufacture of the candidate design. The most promising process plans resulting from this process may be used be used to select the most suitable partners for the virtual enterprise.
