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...

When a dataset involves multiple classes, there is often a need to express the key contrasting features among these classes in humanly understandable terms, that is, to pro"le the classes. Commonly, one class is contrasted from the rest by aggregating the latter into a pseudo-class; alternatively, classes are treated separately without coordinating their pro"les with those of the other classes....

For discrete manufacturers mainline business processes and core business data of the sort, based on workflow and integrated management of the dominant ideology, given the kind of enterprise information system integration of basic principles; On this basis, proposed based on “CAD / CAPP / PLM / ERP “integrated model integration framework to study the integration logic and data model: given based...

— Integrated product development is comprised of CAD, process planning and CNC code generation based on an integrated data structure. To enable various CAD/CAM software solutions to be interoperable, it is necessary to realize reliable and robust information exchange in manufacturing enterprises. To realize interoperability there are two basic approaches: i. To focus on a neutral file format li...

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...

Over the last years, attention in the manufacturing cycle has shifted towards Concurrent Engineering (CE). With this, the integration of the different product life cycle processes has become a focus in both research and industry. However, it is obvious that the integration of all manufacturing processes, taking into account all life cycle aspects from initial functional requirements to final di...

Concepts are proposed to improve the computer support in the (re)design of mechanical products. These concepts are combined with a proposal for an improved link between CAD and CAPP systems. The concepts resulted from a methodic design approach aiming at the design of a re-design support system. Findings from literature, previously conducted research and an object oriented design approach have ...

Modern organization paradigms within manufacturing enterprises have arose in last years, like Agile Manufacturing and collaboration, in order for enterprises to increase their productivity and be more competitive in front of shorter due dates and increasing product qualities required by customers. Most previous works on PLM and currently available systems are usually focused on the use of addit...
