Abstract:
A method for controlling an automatically operated lathe provided with at least one spindle and at least one tool rest, comprising:providing each of a plurality of transfer position data required in a sequence of machining programs in connection with said at least one spindle and said at least one tool rest in a form of a cam-reference data directing a transfer position as a function of a cam rotation quantity; providing a plurality of pulse-train generating sources, each of which generates any pulse train; designating, with regard to each of said plurality of transfer position data, a pulse-train generating source for generating a pulse train defining said cam rotation quantity as one component of said cam-reference data, said pulse-train generating source being selected from said plurality of pulse-train generating sources; and processing each of said plurality of transfer position data provided in the form of said cam-reference data by using said pulse train generated through said pulse-train generating source as designated, to control a relative feed motion between said at least one spindle and said at least one tool rest in said sequence of machining programs.
