Abstract
A measurement/correction system for use in machining an inclined slide core hole includes means for executing a measurement program which, after machining of an intermediate pocket hole in a mold surface, measures the position of the center of a rod hole in a seating surface of the intermediate pocket and the position of the seating surface of the intermediate pocket. Arithmetic means calculates the coordinates of an actual reference point of the rod hole from the measurements. Correction means compares the measured position of the reference point with the reference point previously set in a machining program, and, if there is an error, rewrites the coordinates of the reference point in the program to the measured coordinates. The corrected machining program is executed with the rewritten reference point in order to carry out machining of the core pocket while expanding the intermediate pocket.
