Computer aided process planning (CAPP) has been widely used as an application that is able to plan the in manufacturing with computer technology supporting. In its implementation, stage often requires complete data/information input regarding products will go through several and operations. assembly for example, before what operations be carried out on a parts, assembler must know specification...

Most existing approaches to computer aided process plan ning aim for full automation by searching for a plan that is opti mal with respect to a pre speci ed objective function Such full automation is often infeasible in practice for three reasons i the search space of potential plans is huge ii optimality metrics are often context sensitive and can only be elicited through user interaction iii ...

This paper focuses on the problem of choosing the manufacturing route and characteristics in sheet metal processes, a very important element in computer aided process planning (CAPP) systems. At present, decisions concerning the operations, die, machine and process parameters used in sheet metal are based on experience. One of the objectives of this work has been to develop an activity model to...

In this paper, traditional process design rules for deep drawing of box shapes are used to develop constraints within a dynamic programming (DP) approach to generate a set of alternative optimized process plans that minimize the number of drawing stages and heat treatments. The DP approach is capable of scanning a wide range of different alternative values for process parameters which allows fo...

This thesis presents a new method for Computer Aided Process Planning (CAPP) for a subtractive Rapid Prototyping (RP) process. The “CNC-RP” process uses a 4-axis CNC machining center to create parts with flat end-mills. The objective is to determine the optimal system parameters for the RP process those that enable parts to be created in a shorter amount of time. Two main contributions make thi...

Machining features recognition provides the necessary platform for the computer aided process planning (CAPP) and plays a key role in the integration of computer aided design (CAD) and computer aided manufacturing (CAM). This paper presents a new methodology for extracting features from the geometrical data of the CAD Model present in the form of Virtual Reality Modeling Language (VRML) files. ...

Based on the integration research, one multi-dimension integrated mode of CAPP and PDM was proposed including the integration of knowledge store dimension, knowledge transfer dimension and knowledge application dimension. In the integration of knowledge application dimension, an innovated integration method named key control function module was proposed. In knowledge transfer dimension integrat...
