Abstract
A new methodology is described for the condition monitoring and fault diagnosis of machine tool coolant systems. The steady state characteristics of the coolant system pump outlet pressure, pump motor temperature and tank level are used to define health parameters from which the system health is deduced. On detection of a significant change in system health the pressure transient on closure of the flow valve is captured to aid diagnosis of the fault.
A demonstration system for the coolant system of a Wadkin V4-6 machine tool is described. This is used to verify the usefulness of the health system described above by simulation of a number of typical faults.
