The drilling of accurately located holes in printed circuit cards, or the like, is dependent on the periodic measurement of hole location by the operator to ensure that the holes are within specification. Tying an IBM Personal Computer to the main power system of a hole location measuring machine allows for data accumulation that can anticipate machine error and store data for a variety of analytical purposes. This is particularly helpful in responding to hole location trends or movements that would be imperceptible to an operator. The procedure for accumulating hole-location data is to access the program for the specific product to be checked, enter tracking information, check preset values, and place the probe in the spindle area to be checked.
