The invention discloses a method for controlling regression of a feeding shaft of a processing center to a reference point, which comprises the following steps of: electrifying a machine-tool control device; starting a feeding shaft regress mode; rapidly moving the feeding shaft to a machine-tool reference point at a preset speed; judging whether the feeding shaft reaches a decelerating regress area in the process of rapidly regressing the feeding shaft, and regressing to the machine-tool reference point at a preset low speed after reaching the decelerating regress area; and before the step of starting the feeding shaft regress mode, judging whether the feeding shaft is in an inlay area, if yes, starting the feeding shaft at the preset inlay speed and raising an alarm, at this moment, manually moving the feeding shaft to a fast regress area and then starting the feeding shaft regress mode, and if not, starting the feeding shaft regress mode. Position data of the feeding shaft relativeto a machine-tool coordinate system is read and judged through the machine-tool controller, different zones are differentiated to ensure that the feeding shaft regresses the machine-tool coordinate reference point by adopting the corresponding speed, thus the collision accidents possibly occurring in the process of regressing the feeding shaft is avoided.
