Information processing device and program recording medium

An information processing device, comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to:
• store, at a plurality of times, numerical data related to control or operation of a machine tool that numerically controls a drive axis;
• store audiovisual information including at least one of image information and audio information of the machine tool;
• generate a reference signal indicating a reference time;
• input the reference signal to an audiovisual information acquisition device that acquires the audiovisual information and is configured to output an internal time of a moment in which the reference signal is inputted;
• store the internal time outputted by the audiovisual information acquisition device;
• store a value of the reference signal together with the numerical data;
• synchronize the audiovisual information and the numerical data based on the stored internal time and the stored value of the reference signal;
• and
• output the synchronized audiovisual information, while simultaneously displaying the synchronized numerical data of a time, of the plurality of times, corresponding to the outputted audiovisual information, from among the stored numerical data.

A non-transitory program recording medium which records a program for confirming a machining process of a machine tool that includes a drive axis which is numerically controlled, the program comprising:

• a numerical data storage processing element which stores numerical data related to control or operation of the machine tool at a plurality of times;
• an audiovisual information storage processing element which stores audiovisual information that includes at least one of image information and audio information of the machine tool;
• a reference signal generation element which generates a reference signal indicating a reference time;
• a time information storage element which stores a time of an internal time, from an internal clock of an audiovisual information acquisition device, at which moment the reference signal was generated;
• the numerical data storage processing element stores a value of the reference signal together with the numerical data;
• an output control processing element synchronizes the audiovisual information and the numerical data based on the stored time and the stored value of the reference signal;
• and
• the output control processing element which causes the synchronized audiovisual information stored by the audiovisual information storage processing element to be outputted, while simultaneously causing the synchronized numerical data of a time, of the plurality of times, corresponding to the outputted audiovisual information to be displayed from among the numerical data stored by the numerical data storage processing element.
