The invention discloses a method for achieving RTCP machining on a four-axis horizontal-type machining center. Position sensors are arranged on coordinate axes of an ordinary four-axis horizontal-type numerically-controlled machine tool, real-time values, collected in the machining process, of coordinate positions of a workpiece are transmitted to a calculation device by the position sensors, the coordinate compensation value of the workpiece is calculated in real time by the calculation device according to the distance of the null point of a workpiece coordinate system and the center of the B-axis and the real-time values of the coordinate positions, and the machine tool is controlled by an NC controller according to the workpiece coordinate compensation value provided by the calculation device to adjust machining allowance in real time so that the workpiece can be machined. On the premise that original machining functions of the four-axis horizontal-type machining center are achieved, RTCP machining is achi
