ABSTRACT:
This invention relates to improvements in foundry procedures, particularly in-process and post process inspection with electro-optical sensor units. Principally addressed are: inspection of molds and cores to assure correctness and control procedures to abort pouring if the molds are not correct, inspection of cores on the core line, inspection of patterns for sticking sand, inspection of finished castings for extraneous material in passages, excessive or inadequate stock, correct locator relationships, etc., and control of robotic flash grinders.
Both fixed and programmably moveable sensors are shown in the context of these embodiments.
