Method for operating a numerically controlled production system, and production system for same

A production system, comprising:

• a machine tool for machining a workpiece;
• a numerical controller cooperating with the machine tool and having a control program comprising successive control program sets for path control and interpolation of the machine tool;
• and
• a look-ahead module,
• wherein the look-ahead module is configured to
• generate, prior to a movement, from several successive control program sets for at least one movement axis a movement profile, which comprises guidance variables for a path-time movement for the at least one movement axis for successive clock-cycle points,
• determine with the control program at least one program branching having a plurality of successive alternative control program sections controlled by a condition, with the condition specifying which of the alternative successive control program sections is to be executed depending on the condition, and
• calculate, prior to performing an additional movement, an alternative movement profile for each of the alternative successive control program sections, store the alternative movement profile, and have the alternative movement profile ready at the conditional program branching for carrying out the additional movement.
