Abstract
A method for properly locating a flexible fixture on a CNC machine comprises probing a plurality of locators on a flexible fixture to determine a locator position on a coordinate system for the CNC machine. The position for each of the plurality of locators is analyzed to determine if all of the plurality of locators are within a predetermined offset limit from a nominal position. A controller is programmed with an offset compensation amount based upon the probed position for each locator when each of the plurality of locators is within the predetermined offset limit. The locator positions are adjusted if one of the probed locations is not within the predetermined offset limit. The CNC probing programs are generated by a computer language to accommodate various fixture configurations.
