Iso 6983

STEP-NC is the result of a ten-year international effort to replace the RS274D (ISO 6983) G and M code standard with a modern associative language. The new standard connects CAD design data to CAM process data so that smart applications can understand both the design requirements for a part and the manufacturing solutions developed to make that part. STEP-NC builds on a previous ten-year effort to develop the STEP standard for CAD to CAD and CAD to CAM data exchange, and uses the modern geometric constructs in that standard to specify device independent tool paths, and CAM independent volume removal features. This paper reviews a series of demonstrations carried out to test and validate the STEP-NC standard. These demonstrations were an international collaboration between industry, academia and research agencies. Each demonstration focused on testing and extending the STEP-NC data model for a different application.

A kind of novel open architecture CNC system is put forward based on the key hardware ‘‘PC+PMAC controller’’. The intelligent CNC system is divided into four layers, the field bus is used in it for openness and interoperability. The system software including several functional modules is developed based on COM for reuse and reconfiguration. The proposed open CNC system is based on STEP-NC data model, which aim to provide higher-level information for process control. The framework presented can be used as a reference for STEP-compliant CNC.

Compliant Approach

ISO 14649 standard, commonly recognized as STEP-NC is a data model interface for computer numerical controllers. STEP-NC goes much further that G codes and has a more comprehensive data model that overcomes the lack of process information in ISO 6983 files (G codes programming). The STEP compliant approach brings the possibility to integrate the machine controller to the overall enterprise information network, with the intention of having bi-directional data flow. This will provide the novel capability for upstream feedback of information from the numerical controller to the design and process areas in the process planning and manufacturing. This paper presents the key concepts of the proposed STEP Convertor of the STEP-CNC Mapping System. The objective of the main system is to take a generic STEP file as the input to drive a CNC machine tool. The main system is broken down into two main sub-systems, STEP Convertor and STEP-NC Translator. This paper will focus solely on the information structure and conceptualization of the STEP Convertor.

In order to generate STEP-NC data model in keeping with the ISO14649 protocol, extend the STEP model to the field of the CNC, the paper analyzes STEP standard and its file structure, develops the display software which can be read and display the STEP format file based on open source Open CASCADE geometric kernel by using the Visual Studio 2008 software development environment, designs one instance by using Pro/E software, and stored as a STEP format file in Pro/E environment, and then, using the software developed to read and display the STEP file. The results of this study improve the product data exchange and integration capabilities, lay a good foundation for generating the STEP-NC format file in the future, extracting the file STEP-NC machining information, and achieving CAD / CAM / CAPP integration system.

Iso 6983

STEP-NC (ISO 14649) is a newly developed and feature-based machine tool control language for CNC controller. In contrast with conventional G&M code (ISO 6983), this new data model could almost transmit all the designing and planning information for machining parts through CAD&CAPP&CAM to CNC. However, STEP-NC is feasible but not enough to support some intelligent actions such as self-planning, self-learning, decision-making, etc. A complete and well-structured knowledge base is urgently needed to be established to support CNC intelligence. The main work of this paper is focused on two fields: i) An extraction, presentation and utilization mechanism for ontology-based machining knowledge is implemented. ii) A novel framework for STEP-Compliant and knowledge-base supported intelligent CNC controller is proposed.

New Generation

In this paper, we present a conceptual framework for designing and implementing an intelligent CNC system. The architecture and functional modules are derived from requirement analysis, and they are designed to have a thinking capability before, during, and after the execution of the manufacturing task, so that the assigned task can be effectively executed while dealing with unexpected changes occurring on the shop floor. Also, the data model for supporting the architecture is addressed based on the STEP-NC data model or ISO 14649. The framework presented can be used as a paradigm for new generation intelligent STEP-compliant CNC.
