Intelligent STEP-NC-compliant setup planning method

Journal of Manufacturing Systems, 2022
Abstract This paper proposes an intelligent STEP-NC-compliant setup planning method with the combination of rules, analytic hierarchy process (AHP) and improved back propagation neural network (IBPNN). In the method, the STEP-NC-compliant manufacturing features are firstly automatically and reasonably grouped based on tool approach direction (TAD ...

Realization of STEP-NC enabled machining

Robotics and Computer-Integrated Manufacturing, 2006
Abstract A STEP-compliant CNC machine tool that demonstrated a G-code free machining scenario is presented. The aim of this research is to showcase the advantages of, and evaluate, STEP-NC—a new NC data model—by implementing it in a legacy CNC system.

Testing STEP-NC implementations

Proceedings of the 5th Biannual World Automation Congress, 2003
STEP (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.

Enabling Machining Vision Using STEP-NC

ASME 2012 International Manufacturing Science and Engineering Conference, 2012
STEP-NC is a new data format for manufacturing control. One of its applications is to enable integrated on machine measurement of machining processes using vision systems and other sensors. In this paper we describe the manufacturing process and manufacturing resource models in STEP-NC that can be used to enable this type of measurement.

Arbeitsschrittplanung beim Drehen mit STEP-NC

Zeitschrift für wirtschaftlichen Fabrikbetrieb, 2002
KurzfassungDie Arbeitsfolge bei der Bearbeitung eines Werkstücks beeinflusst neben der Oberflächengüte auch die Bearbeitungsdauer. Das Erstellen einer optimierten Arbeitsgangfolge ist unter anderem abhängig von den Erfahrungen des Projekteurs und bedarf einer entsprechenden Projektierungszeit.

Lessons learned implementing STEP-NC AP-238

International Journal of Computer Integrated Manufacturing, 2006
STEP-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.

STEP-NC and the Future Manufacturing

2021
The 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-
