چکیده:
Energy efficiency remains one of the major issues in the machining domain. Today’s machining systems
are confronted with a number of new challenges, such as turbulent product demand and variations in
production resources. Rapid and flexible energy modelling in a distributed and collaborative machining
environment emerges as a new research area. Energy demand models in such an environment need to be
practical, accurate, effective, scalable and reusable. Energy analysis and optimisation cannot be carried
out once for all at the beginning. Instead, it is an on-going process. In this paper, the function block
technique, i.e. IEC 61499, is used for the development of energy demand models as it brings advantages
such as modularity, encapsulation, extensibility and reusability. A brief review on energy modelling
and research on function blocks are given in the first part. A novel energy demand modelling approach
based on function blocks is then proposed and elaborated. Three types of function blocks have been
developed, i.e. machine tool dependent function blocks, state transition function blocks, and service
interface function blocks. The first type, as the fundamental building blocks, is divided into two sub-types,
machine component function block and machining state function block. Two case studies, based on a small
3-axis milling machine and an industrial production line respectively, are presented to demonstrate
the possible applications using the function block-based model. Comprehensive discussions are given
thereafter, including a pilot application of a distributed process planning system and a unique energy
evaluation scheme. A confidence level associated energy rating system is proposed as the first step to
turn energy consumption figures into useful indicators. The energy demand model based on function
blocks developed here enhances the energy modelling and their practical implementations.
