4. Result and Discussion
In the present work, the permanent index have been calculated for the standard operating conditions of the
process parameters or the attributes for the desired objectives like increase in the metal removal rate. It has been
observed that the permanent of the sub-groupings for the attributes gives the informative knowledge related to
the Electric Discharge Machining process. The subgrouping permanent function gives information related to its
effect on the overall permanent functional value for an attribute variation. Since, various graphs as available in
the technical documents of the EDMs as well as experimental data for the Electric Discharge Machining process
are used for developing and analyzing the logical interdependencies of the attributes along with their inheritance
factors on the machining process, so the results during the sensitivity analysis as carried out in previous chapter
is an alternate representation of the Electric Discharge Machining Process which can be used ahead for
simulating the process under the extended limits of the process constraints or the attributes.
The variation in the process index i.e. the permanent of the logical matrix developed also gives the same effect
on the desired objective of material removal rate for the Electric Discharge Machining process. Hence, the efforts
done for the logical representation of the process is found to be satisfactory in terms of usage of graph theoretic
approach as a tool for simulating such process constraints and further benchmarking of the process.
