Control device

A control device, comprising:

• a memory that stores a program;
• and
• a processor configured to execute the program and control the control device to:
• extract each of a plurality of task items including at least creating/editing a machining program, selecting a machining program, measuring and setting a workpiece, setting a tool, and setting a custom macro variable in setup work for next machining by a machine tool as a mandatory setting or an optional setting based on a machine configuration including at least one of a number of axes and a number of systems of the machine tool to be set;
• detect an operation content of an operator's operation on the machine tool;
• dynamically determine whether each of the plurality of task items extracted as a mandatory setting or an optional setting corresponds to either a mandatory setting or an optional setting when there is at least a change in the machining program of each system, a change in the tool number or tool offset value of each system, a change in workpiece coordinates, or a change in a custom macro variable in operation contents in the setup work for the machine tool during a period from completion of most recent machining performed by the machine tool to a present time, and update a task status of a task item from an uncompleted or unupdated status to a completed or updated status when at least a save operation in the task item of creating/editing the machining program, or at least a setting operation in the task item of selecting the machining program, measuring and setting the workpiece, setting the tool, or setting the custom macro variable is detected;
• and
• not to permit a machining operation by the machine tool when a task item as an uncompleted or an unupdated mandatory setting remains among the plurality of task items.
