Process planning is an essential component of computer aided process planning (CAPP), which involves operations selection from design features and operations sequencing of these selected operations. It makes process planning a complex combinatorial optimization problem to conduct of these two steps simultaneously. In this paper, we propose a cooperative simulated annealing (CoSA) approach for t...

Presented in the paper is a C-space based computer automated process planning (CAPP) algorithm for freeform die-cavity machining, which is an extension of the hierarchical CAPP model proposed earlier by the authors. In order to demonstrate its validity, the proposed CAPP algorithm has been implemented and applied to actual die-cavity machining examples. q 2002 Elsevier Science Ltd. All rights r...

In process planning, how to obtain an optimal process planning is the essential of computer-aided process planning (CAPP) system. The main goal of CAPP system is to derive manufacturing features and machining operations from a design model and sequence the machining operations of the part in a feasible (by some technological constraints) and effective (by some economical standards) order. In th...

Computer-Aided Process Planning (CAPP) is considered to be the bridge that links Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM). One of the imperative characteristics of CAPP is Automatic Feature Recognition (AFR). CAD files contain detailed geometric information of a part, which are not suitable for using in the downstream applications such as process planning. Different CA...

Computer aided process planning (CAPP) and scheduling are two major activities in a modern manufacturing system. The existing CAPP systems have not taken account of shop floor conditions while developing process plans. This paper discusses the importance of integration of scheduling and CAPP and proposes a method for the same. There can be several methods to machine a part and several machines ...

The new standard ISO 14649 provides CAD/CAPP/CAM/CNC with an interface and a comprehensive high level and detailed manufacturing information. CNC technology based on STEP-NC will be the future trend, and the intelligent process planning is the core of STEP-NC oriented CNC technology. The objective of this research is to present the architecture, key technologies and implementation of STEP-NC or...

Computer-aided process planning (CAPP) is an important interface between computer-aided design (CAD) and computer-aided manufacturing (CAM) in computer-integrated manufacturing environments (CIMs). In this paper, process planning problem is described based on a weighted graph, and an ant colony optimization (ACO) approach is improved to deal with it effectively. The weighted graph consists of n...

In times of global crises, the resilience production chains is becoming increasingly important. If a supply chain interrupted, cost-effective solution must be established quickly. context Industry 4.0, concept smart manufacturing offers for fast and automated decision-making in planning. The core idea digitalization product life cycle linking individual phases this cycle. Computer Aided Process...

The assembly sequence optimization problem is challenging as number of sequences rises staggeringly with part count making it combinatorially explosive, tedious and time consuming to solve. A Computer-Aided Process Planning (CAPP) system for robotic assembly by a discrete cuckoo search algorithm has been proposed by us to generate feasible and optimal sequences considering minimization of orien...

Feature extraction and classification is considered as the bridge between Computer-Aided Design (CAD) and Computer-Aided Process Planning (CAPP). This paper proposes a method that can extract and classify turning (including symmetric and non-symmetric) and non-turning features that are concave, convex, or complex for rotational parts taking a 3D data file as input. In addition, feature interact...
