Automated synthesis of manufacturing process plans has been attempted through many methodologies for a wide range of manufacturing problems. In some cases, such as the manufacture of machined parts, these attempts have not been fully successful: to date, it has not been possible to develop purely generative systems to synthesize complete realistic plans for a wide range of realistic machined pa...

Fixture design is crucial part of manufacturing process. Fixture design is a critical design activity process, in which automation plays an integral role in linking computer-aided design (CAD) and computer-aided manufacturing (CAD). This paper presents a literature review in computer aided fixture design (CAFD) in terms of automation and optimization techniques over the past decades. First, the...

Automatic Feature Recognition (AFR) is considered as the key connection technique of integration Computer Aided Design (CAD) and Process Planning (CAPP). At present, there a lack systematic method to identify evaluate local features 3D CAD models. The process information such topological structure, shape size, tolerance surface roughness should be considered. Therefore, novel Model Based Defini...

The objective of this project is to study on the integration of Neural Network in Computer Aided Process Planning especially in feature recognition application. An introduction about process planning will be covered in brief. Following this, the concept of feature shall be discussed as an integral part in CAPP. The next section presents one of the feature recognition methods developed by Nezis ...

This paper presents an intelligent process planning system using STEP features (ST-FeatCAPP) for prismatic parts. The system maps a STEP AP224 XML data file, without using a complex feature recognition process, and produces the corresponding machining operations to generate the process plan and corresponding STEP-NC in XML format. It carries out several stages of process planning such as operat...

This paper describes the development and validation of a computer numerical controller architecture adherent to the standard STEP-NC Part-11 that is associated with the milling process. The STEP-NC controller development is based on the open source driver EMC (Enhanced Machine Controller or LinuxCNC) adherent to the standard RS-274 that originally works with the NC program using codes G/M (G-co...
