Computer-aided process planning (CAPP) is an essential component in linking computer-aided design (CAD) and computer-aided manufacturing (CAM). Operation sequencing in CAPP is an essential activity. Each sequence of production operations which is produced in a process plan cannot be the best possible sequence every time in a changing production environment. As the complexity of the product incr...

Development of information technology industry provided great possibilities in the area of integration of diff erent CAx systems, such as CAD, CAM, CAE and others. In order to successfully link systems of automated-design (or Computer Aided Design CAD) with automated manufacturing systems (or Computer Aided Manufacturing – CAM), automation of manufacturing process planning is needed, i.e. CAPP ...

An important process-planning task in sheet-metal manufacturing is the determination of bending sequences for individual components. Computer-aided generation of these sequences, as part of a computer-aided process-planning (CAPP) system, can relieve the workload of process-planning departments, this being especially important in small batch manufacturing environments. This paper discusses the ...

This investigation addresses distributed environments for computer-aided process planning (CAPP) over a network. The Java 2 Enterprise Edition (J2EE) standard using Java is applied to implement cross-platform and distributed computing architecture, thus reducing the system loading during manufacturing process planning. The product-oriented standard, standard exchange of product (STEP), model da...

Abstract: A framework for dynamic classification with computer aided process planning (CAPP) systems is presented. The dynamic classification is used to provide flexibility facility status information while the CAPP system is used to modify the retrieved process plans. The paper deals with aspect of classification systems in CAPP systems based on Group Technology (GT). The dynamic classificatio...

The paper deals with new classification methods in Computer Aided Process Planning (CAPP) systems which extend the possibility of engineering part classification. New developed methods of classification – selective and dynamic classifications will be introduced and described in the paper.

Computer-aided process planning (CAPP) is an important and complex in the computer integrated manufacturing system(CIMS). The expression methods of process knowledge based on manufacturing feature is established based on the analysis of characteristic of process knowledge. According to the constraints mong process knowledge, decision space of process planning based on process constraints is con...

In this paper, the problem of minimizing the number of drawing stages and heat treatments needed for the multi-stage deep drawing of cylindrical shells is addressed. A conventional rule-based computer-aided process planning (CAPP) is utilized within a dynamic programming approach to generate a set of alternative optimal process plans. A finite element analysis is carried out to guide the select...

Considerable research and development efforts have been devoted to Computer Aided Process Planning (CAPP). Nevertheless, because the CAPP problem is complex and is characterized by many interdependent technical and business parameters and variables, no viable off-the-shelf solution is yet available that can be easily or widely implemented in industry. This paper presents an overview of the CAPP...
