PURPOSE: A standard point establishment method of a tool position is provided to minimize a machine work and accurately distinguish the tool position by conveniently and accurately establishing a longitudinal direction center line of a tool for the machine work with a standard point of the tool position. CONSTITUTION: A standard point establishment method of a tool position comprises as follows. A laser beam is irradiated from a laser with a light detector according to a predetermined direction (S10). A tool desiring the establishment of a standard point between the laser and the light detector is moved at a fixed distance as a fixed interval according to the direction which is at right angles to an irradiated direction of the laser beam (S20). When the tool is overlapped with the laser beam by moving between the laser and the light detector, the strength of the laser beam is measured by receiving the laser beam irradiated in a laser beam irradiating step (S40). The strength of the laser beam measured in a laser beam strength measuring step is converted into the intensity of an output voltage (S50). A point in which the intensity of the changed output voltage converted in an output voltage converting step is minimally set up as the standard point of a tool moving direction axle (S60).
