| Summary: | Modern manufacturing industries demand computer numeric controllers, having higher level input
languages than outdated G-code, and less proprietary vendor dependencies. IEC 61499 is a new
standard for distributed measurement and control systems, that enables portability and interoperability
of embedded controllers, along with the ease of their mapping to arbitrary distributed networking
hardware configurations. This paper demonstrates that the IEC 61499 reference architecture can be
successfully used to create a computer numeric controller, offering interoperability, portability,
configurability, and distribution characteristics. The layered CNC-FB architecture is proposed, which
simplifies the design of a CNC machine controller with the architecture layers responsible for data
processing, data storage and execution. In combination with the object-oriented Model-View-Control
design pattern, the CNC-FB architecture supports the design framework, in which simulation of the
machining becomes natural and inherent part of the design process, with seamless transition from
simulation to actual machining. The implemented controller was tested in both the model and on an
actual milling machine. |
