Fig 2 (a) & (b) Nozzle End Dome Side; (c) Nozzle End Metal Tongue Side; (d) Head End Metal Groove Side; (e) Middle Metal Groove Side As per the Tables 3, 4,5,6,7 and Figure 2 following inferences can be drawn:  For each variant of segment the equation generated shows that the deviation from the required depth varies in third degree of axial/radial depth values required from the reference surface. This indicates that there is high variation in values as the machining operation progresses to final value.  To predict the deviation from the required depth, the third degree equation for each graphical representation gives the idea to change the work offset for consecutive cuts. This change in work offset directly brings out the change in the depth of cuts to be followed.  Inspection at every stage takes approximately 20-25 minutes. By taking the advantage of graphical representation, some stage inspection could be skipped & thus the total machining operation time could be reduced.
