A workpiece cut detecting method for an NC lathe is provided to reduce costs and improve space utilization by carrying out a cut detection process through software. A workpiece cut detecting method for an NC lathe includes a step of selecting a detecting tool from tools except for cutting tools, a step of inputting a cut detection start point and a cut detection end point of the detecting tool, a step of measuring a motor load at a no-load state one or more times when the detecting tool moves from the start point to the end point, a step of automatically inputting maximum and minimum allowable motor load values by adding and subtracting a predetermined value to and from the maximum and minimum values of the measured motor load, and a step of emergently stopping a machine in case where the measured motor load value exceeds the minimum and maximum allowable motor load values.
