A method for controlling an automatically operated lathe provided with at least one spindle and at least one tool rest includes the following steps. First, each of a plurality of transfer position data required in a sequence of machining programs in connection with at least one spindle and at least one tool rest is provided in a form of either one of two types of transfer position data, one of which is cam-reference data directing a transfer position as a function of a cam rotation quantity and the other is time-reference data directing a transfer position as a function of an elapsed time. Next, a time-series allocation of the cam-reference data and the time-reference data is designated in the sequence of machining programs. Then, the cam-reference data and the time-reference data are processed in accordance with the time-series allocation, so as to control a relative feed motion between at least one spindle and at least one tool rest in the sequence of machining programs.
