Intelligent Control of CNC System Based on IEC 61499 Function Block Technology

摘要

For being more competitive, more productive and more cost effective, machining industry requires a numerous change that are not only involving implementation method but also technology improvements. The major challenge is to find new solution for synergize the computer numerical control (CNC) machine tool control system capability to be more flexible and adaptable towards intelligence of next generation CNC machine tool. Availability of high level and detailed information data interface in CNC machine tool system provides real opportunity and challenge to promote the improvement of CNC system intelligent capability. One of famous research recently was the development of ISO 14649 (STEP-NC) as a next generation of data model interface for CNC system. However, STEP/STEP-NC is a passive data interface model which not contain any intelligent functionality. Therefore, there are still a lot of works must be done and more dynamics approaches needed for enhancing intelligent functionality to the STEP-NC compliant CNC system. This will eventually make next generation CNC system can be fully developed. The aim of this paper is to analyse the potential of IEC 61499 function block as enabler technology in enhancing intelligent functionality for next generation CNC system.
