The Part: Mold insert
Couple of hundred free form surfaces
The Process: Verify the accuracy of the insert against the CAD model
Results are either color-coded (Fig. 1) based on the tolerance used or the actual deviations are displayed next to the points (Fig. 2) in the desired units as actual deviation from nominal geometry (in this example the part is metric). Up to 14 user selectable colors can be used.
The Results: The NC operator used oversized cutter resulting in excess material being removed from the vertical walls (points in blue). The part needs to be re-cut.
Highlights: Complete the job in only 20 minutes by scanning 2000 points on machine equiped with scanning head. The time to run SPV was under 2 minutes.
