NC program creating device

A device for creating a numerical control (NC) program for use to control a machine tool, the device comprising:

• a memory that
• stores a standard code that performs a prescribed operation and that is restricted from being executed simultaneously with an operation of moving a feed mechanism in a non-cutting state;
• and
• stores a simultaneous execution code that corresponds to the standard code, that performs part of the operation of the standard code, and that is allowed to be executed simultaneously with the operation of moving the feed mechanism in the non-cutting state;
• and
• processing circuitry that
• determines whether the standard code is in the NC program before or after a non-cutting feed code that starts the operation of moving the feed mechanism in the non-cutting state and that verifies that the feed mechanism has reached a command position;
• places, instead of the standard code, the simultaneous execution code before the non-cutting feed code;
• and
• places a code, after the non-cutting feed code, that performs at least the prescribed operation of the standard code other than the operation of the simultaneous execution code when the processing circuitry determines that there is the standard code, wherein the standard code includes an automatic tool changer (ATC) code that sequentially performs operations of opening a shutter, changing tools, and closing the shutter, the simultaneous execution code corresponds to the ATC code and the simultaneous execution code is a shutter open code that performs the operation of opening the shutter,
• when the ATC code is located after the non-cutting feed code, the processing circuitry inserts the shutter open code before the non-cutting feed code, and
• the NC program is used to control the machine tool.

• the standard code includes a clamp code that starts an operation of clamping a rotary table that is unclamped from a support mechanism for the rotary table and that verifies that the rotary table has been clamped,
• the simultaneous execution code corresponds to the clamp code and the simultaneous execution code is a clamp start code that starts the operation of clamping the rotary table,
• the code performs at least the prescribed operation of the clamp code other than the operation of the clamp start code,
• when the clamp code is located before the non-cutting feed code, the processing circuitry deletes the clamp code,
• inserts the clamp start code before the non-cutting feed code, and
• inserts the code at a position located atler the non-cutting feed code and before a cutting feed code, and
• the NC program is used to control the machine tool.
