1) Panel checking—The typical con- siderations are accurate part measure- ment within the tolerances provided by GD&T, although tolerances typically have changed to the extent that finding tolerances of + 0.1mm on any given part is not uncommon.
2) Die checking—This allows the reengineering of dies by scanning an existing die, either for duplication or for recutting a damaged die.
3) Scanning of castings—This prac- tice can eliminate the unproductive and wasteful air cutting that can occur in machine shops.
The development of blue-light (LED) technology for panel scanning represents a significant step in the right direction for this technology, since the data is less affected by ambient lighting and significantly improves the quality of the data collected.
Data collected from scanners is not instantaneously available, since there is considerable setup time on a nonau- tomated, manually operated system. And, a scanner attached to the end of a robot is limited to scanning panels that already have been set up.
Which System is Best?
None of the systems described here meet all of the requirements of speed, data quality and coverage of the panel or die. White/blue-light scanning seems to be the process of choice for most die manufacturers and stamping houses. In particular, the advent of blue-light scanning systems seems to bring the scanners closer in ability to the dimensional accuracy of a CMM. However, portable CMMs will continue to find use for comparison purposes, to ensure that the data reflects what is seen in the body shop.
The use of rails, calipers and step, feeler and pin gauges will continue to play a significant role in applications requiring quick measurement of panel dimensions, but most fixtures will have limited rails around them. This will allow stamping plants and die shops to make quick decisions while waiting to obtain data from CMM or white/blue light inspections. MF
