Abstract

The paper demonstrates how a Petri net based on a hierarchical structure block diagram can be used to model and control all the activities within an flexible manufacturing cell (FMC). Next by utilising fuzzy Petri nets, a technique based on 9 fuzzy rules is developed. The tool speed (s) and the feed rate (r) throughout the milling operation are used to determine surface finish (f´). It also illustrates how fuzzy Petri nets with neural networks can be used for the modelling and control of surface finish. The surface finish represents the quality specification of output products from CNC-milling machine within an FMC
