<p>A method for machining a slide core hole and a measurement/correction system are provided to efficiently machine the slide core hole by using the high-speed cutting performance of a five-axis machine tool. A method for machining a slide core hole includes the step of pivoting a spindle head(10) to be suitable for the inclination angle of the slide core hole machined in a mold and securing the angle of an A axis, the step of spot facing a hole in a thin and flat bottom of the mold using an end mill, the step of drilling a guide hole in the bottom of the spot-facing-type hole using a drill or reamer, the step of drilling a rod hole using the guide hole as a guide part for a gun drill and the gun drill as a tool, the step of forming a middle pocket hole while expanding the spot-facing-type hole using the end mill, the step of correcting a reference point depending on the measured result of the middle pocket shape, and the step of executing a corrected machine program having the corrected reference point to precisely form a core pocket while expanding the middle pocket using the end mill.</p> |
