It has been observed from that the specimens have taken a curl shape due to uneven thermal contraction. This
effect of curl has been reported in the measurement of the thickness direction. A Metzer-M binocular stereo zoom
microscope (Model METZ - 218/VISION PLUS 7000 BZM) has been used to obtain the microscopic images. The
thus obtained images have been measured for this extra dimension using Material Plus software. In order to correct
the effect of curl resulting in the measurement of thickness by vernier, the curl as obtained from the software has
been subtracted from the thickness. Now the thickness has been adjusted to the original thickness excluding the
effect of curl. Figure 1 provides the microscopic picture of one of the specimens and the evaluation of curl as
observed. Once the corrected thickness has been arrived the volume of the part has been obtained and it is reported
as shown in Table 2.
