Automatic programming system

An automatic programming system for a two-saddle NC turret lathe, comprising:

• machining step manual input means, connected so as to be manually operable by an operator, for receiving manually input shape definition data defining a machining condition for each of a plurality of machining steps, for receiving machining data including at least a tool designation and a machining speed and for receiving a manually input machining code identifying each machining step;
• memory means for storing the received shape definition data and the received machining data in accordance with the received machining code;
• machining assigning/setting means for manually assigning a series of the machining steps to be performed by each saddle by manually inputting either a machining code indicating the machining condition at each machining step or a wait command designating one saddle to wait for completion of machining by the other saddle;
• and
• program creating means for automatically creating a machining program for each saddle in accordance with the machining codes and the wait commands manually input by said machining assigning/setting means to corresponding saddles at each machining step, and the shape definition and machining data stored in said memory means.
