STEP integration of CAD/CAM & CAPP in numerical control machining

Abstract

In manufacturing, Numerical Control (NC) was a revolutionary innovation while the development and application of Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) has boosted manufacturing greatly. However, there have been "walls" between CADICAM and the workpiece processing on the shop floor.Fortunately, thanks to the international collaborative research projects, we now have the "Standard for the Exchange of Product model data ", known as "STEP", which are industrial automation systems and integration product data representation and exchange. These systems are able to describe product data covering the entire IifecycIe of a product, independent from any particular system. This description is of such nature as it is not only fit for neutral file exchange but also serves as a basis for executing and sharing product databases and archiving.

A review on Utilizing Ontological Approaches in Integrating Assembly Design and Assembly Process Planning (APP)

“…Under the interfacing and the file-based approaches (Fig. 1) several literature examples are listed for integrating product design and some manufacturing planning applications, such as CAD-CAX integration [29], CAD and Computer Aided Process Planning (CAPP) integration [30,31], CAD/CAM and CAPP integration [32], CAD/CAM/CAE integration [33], and CADmanufacturing process planning integration [34,35,36]. Many other examples can also be found in the published literature.…”
