This invention converts a toolhead of a computer numerical controlled machine into a locating fence by installing a fence guard on the toolhead. Since there is an indexing program in a computer numerical controlled machine to monitor a real time location of a spindle relative to a worktable, the true location of the locating fence can be easily obtained by adding an offset value indicative of the characteristic of the fence guard to numerical data indicative of the real time location of the spindle.
