| Summary: | Today with the latest technology the information beyond tool movement and
switching instruction such as tooling, manufacturing features and process sequences are
needed to support global adaptability for manufacturing with a specific focus on CNC-based
manufacture. This research focuses on the use of the new standard; ISO 14649 (STEP-NC),
to address the process planning and machining of discrete turn/mill components and proposes
a STEP Compliant NC structure for generation of ISO 14646 code which can be used for
turning component manufacture. The novel application of this work is STEP-NC compliant
process control where the research will utilise and extend the standard for in process
measurement at the machine and also explore the application and integration of the STEP-NC
standards. The major contribution of this research is the review of a computational
environment for a STEPNC compliant system for turn/mill operations by focusing the
outlines of the three major CAD/CAM frameworks to support the implementation of the
standard with various levels of STEP compliant architecture. Issues related to the
implementation of these frameworks and their use with STEP compliant NC controllers
provide a major change in the current day use of CAD, CAPP, CAM and CNC systems. This
change will bring new challenges to industrial users and software vendors to identify the new
boundaries and define intelligent CNC manufacture in the 21st century. |
