Method and system for controlling a machine tool

A control system for a machine tool, comprising a first buffer memory, a second buffer memory, a processor unit and an input interface, wherein the processor unit is configured to

• process a parts program by executing non-cyclic preprocessing run tasks and cyclic main run tasks;
• store two master values resulting from the executed non-cyclic preprocessing run tasks in the first buffer memory, wherein each of the two master values corresponds to a respective position for a master axis, with each of the respective positions being assigned to a respective cycle of the cyclic main run tasks;
• generate a first part of a curve table, wherein the first part of the curve table includes a first specification that assigns a first one of the two master values to a first coupling value for a coupling axis;
• store the first part of the curve table in the second buffer memory;
• based on the first master value and the first coupling value, execute the respective cycle of the cyclic main run tasks to which the first master value is assigned;
• after execution of the respective cycle of the cyclic main run tasks, discard the first specification and generate a second part of the curve table, wherein the second part of the curve table includes a second specification that assigns a second coupling value for the coupling axis to a second one of the two master values;
• and
• store the second part of the curve table in the second buffer memory.

A computer program embodied in a non-transitory computer-readable storage medium and comprising commands, which when the computer program is executed by a processor unit of a control system, prompts the processor unit to

• process a parts program by executing non-cyclic preprocessing run tasks and cyclic main run tasks;
• store two master values resulting from the executed non-cyclic preprocessing run tasks in a first buffer memory, wherein each of the two master values corresponds to a respective position for a master axis, with each of the respective positions being assigned to a respective cycle of the cyclic main run tasks;
• generate a first part of a curve table, wherein the first part of the curve table includes a first specification that assigns a first one of the two master values to a first coupling value for a coupling axis;
• store the first part of the curve table in a second buffer memory;
• based on the first master value and the first coupling value, execute the respective cycle of the cyclic main run tasks to which the first master value is assigned;
• after execution of the respective cycle of the cyclic main run tasks, discard the first specification and generate a second part of the curve table, wherein the second part of the curve table includes a second specification that assigns a second coupling value for the coupling axis to a second one of the two master values;
• and
• store the second part of the curve table in the second buffer memory.
