This paper reports a practical method descrbing the box parts information, using the shape set and the shape code set, in computer aided process planning(CAPP).
In the engine cylinder body computer aided process planning(CAPP) system development,the structure and manufacturing feature of the cylinder body are analyzed firstly. The cylinder body's product feature model is then created in terms of CAPP system's demand using the Pro/Engineer software.
Computer aided process planning (CAPP) has been regarded as not only an important research area for the informatization on shop-floor level, which presently remains a relatively weaker sector in information-based manufacturing, but also a bridge across the informatization of shop-floor and enterprise levels.
In view of the lower automatic level of block assembly process design, that will negatively influence construction period and quality in shipbuilding, a computer aided process planning (CAPP) system newly developed is presented in the paper. On the basis of case based reasoning the research focuses on the key techniques in assembly sequence planning, including block assembly information model, index structure of case library, case representation based on object oriented technology, similarity degree algorithm in reasoning process and assembly sequence match based on genetic algorithm, etc.
It is extremely important for procedure of process design and management of process data for product life cycle in Computer Aided Process Planning (CAPP) system, but there are many shortcomings with traditional CAPP system in these respects.
This paper deals with the role, advantages, problems and solution techniques for the implementation of dynamic Computer Aided Process Planning (CAPP) systems in a Felxible Manufacturing system (FMS).
In order to discover the typical process route in the process planning database from the Computer Aided Process Planning (CAPP), Knowledge Discovery in Database (KDD) is applied.
This paper describes a new data model of CAPP(Computer-Aided Process Planning). It consists of two components: product model and method model.Product model expresses all process states of product. Method model is about process methods and process constructs. In CAPP data model, product information drivers method model, and method modifies product data. And so, the relationship between product and process method is established. The data model, which can express general product's process planning,...
The paper presents a model for CAPP(computer aided process planning) sys-tem, which integrates process data together in an open structure. The model consists oftwo components. The first is to construct improved class hierarchy. According to industryclassification standards, process sources are Abstract:ed and generated to form reusable andderivable classes that describe process source by inheritance, or through schema evolution.The second is to build communications among forrn feature, process device ...
