Testing STEP-NC implementations
Proceedings of the 5th Biannual World Automation Congress, 2003STEP (STandard for the Exchange of Product model data, ISO 10303) data for numerical control, or STEP-NC, is intended to provide full product and process data interoperability between computer-aided manufacturing systems and machine tool controllers.

A framework for machining optimisation based on STEP-NC
Journal of Intelligent Manufacturing, 2010Inappropriate machining conditions such as cutting forces cause tool failures, poor surface quality and worst of all machine breakdowns. This may be avoided by using optimal machining parameters, e.g. feed-rate, and continuing to monitor it throughout the machining process.

STEP-NC and the Future Manufacturing
2021The aim of the future Computer Numerical Control (CNC) system is to be intelligent, adaptable, open, and flexible. However, the current data interface model (ISO 6983) is found to be not capable enough to meet the future challenges because of various limitations. Therefore, the new data interface model STEP-NC (Standard for The Exchange of Product Data-

STEP-NC- and XML-enabled e-manufacturing
International Journal of Computer Applications in Technology, 2006STEP-NC is a newly developed international standard (ISO 14649), which extends the STandard for Exchange of Product model data (STEP) geometric data exchange standard into the manufacturing domain by defining a bidirectional interface between Computer-Aided Manufacturing (CAM) systems and Computerised Numerical Control (CNC) controllers.

STEP-NC Based Manufacturability Evaluation
2010This paper presents an evaluation method for part manufacturability. The data model used is the STEP-NC data model, i.e. ISO 14649. Firstly, the evaluation indices such as workpiece clamping, performance of machine tools, resources of cutting tools and auxiliary performances are presented.

Development of STEP-NC for intelligent machining
2017 International Conference on Advances in Mechanical, Industrial, Automation and Management Systems (AMIAMS), 2017G-M codes have been used since decades and now have become obstacle in intelligent manufacturing. G-M codes only gives motion to the tool across the workpiece. It does not provide high level information of operation and feature to the machinist, who is completely unaware of operability of these codes.

Dealing with feature interactions for prismatic parts in STEP-NC
Journal of Intelligent Manufacturing, 2008Determining the precedence of machining features is a critical issue in feature-based process planning. It becomes more complex when geometric interaction occurs between machining features. STEP-NC, the extension of STEP (ISO 10303) standard developed for CNC controllers, is a feature-based data model.

Lessons learned implementing STEP-NC AP-238
International Journal of Computer Integrated Manufacturing, 2006STEP-NC AP-238 is an integrated version of the STEP-NC ISO 14649 standard that enables more data sharing with the other STEP standards for CAD, CAM and CAE applications. This paper describes how STEP-NC AP-238 is being tested for deployment in the United States of America.

Development of a data interface for rapid prototyping in STEP-NC
International Journal of Computer Integrated Manufacturing, 2006Layered manufacturing (LM) technologies, usually referred to as rapid prototyping (RP), have the ability to create a physical part directly from their computer model by adding materials on a layer-by-layer basis. Once a computer model is generated for a physical object, it needs to be communicated to other computer systems or LM machines to be further ...
