Apparatus, controller, and method for generating image data of movement path of industrial machine

An apparatus configured to generate image data of a movement path of an industrial machine, the apparatus comprising:

• a processor configured to:
• generate the movement path of the industrial machine when performing a work on a workpiece;
• acquire running information of the industrial machine when performing the work on the workpiece;
• generate image data in which a first point on the movement path corresponding to a change point of first running information, and a second point on the movement path corresponding to a change point of second running information different from the first running information are highlighted on the movement path in display forms visually different from each other,
• wherein a position of a defect generated in a surface of the workpiece when the industrial machine performs the work on the workpiece in accordance with a machining program matches the highlighted image data on the movement path,
• wherein the running information includes time-series data that indicates, in time-series, a change of the position, the velocity, the acceleration, the jerk, the movement direction, or the running mode with respect to time, and
• wherein the processor is further configured to:
• change a parameter of the running information in the machining program based upon the highlighted change points to control an operation of the industrial machine, and acquire, in the time-series data:
• the change point at which a change amount of the position, the velocity, the acceleration, the jerk, or the movement direction within a predetermined time exceeds a predetermined threshold value;
• or
• the change point at which first running mode is switched to second running mode.

An apparatus configured to generate image data of a movement path of an industrial machine, the apparatus comprising a processor configured to:

• generate the movement path of the industrial machine when performing a work on a workpiece;
• acquire time-series data that indicates, in time series, a change of running information of the industrial machine with respect to time, during performing the work on the workpiece;
• retrieve, from the time-series data, a first change point of first running information, determine, in the time-series data, a first time point at which the first change point occurs, and specify a first point on the movement path corresponding to the determined first time point;
• retrieve, from the time-series data, a second change point of second running information different from the first running information, determine, in the time-series data, a second time point at which the second change point occurs, and specify a second point on the movement path corresponding to the determined second time point;
• generate image data in which the first point and the second point are highlighted on the movement path in display forms visually different from each other;
• and
• change a parameter of the running information in a machining program of the industrial machine based upon the highlighted first point and the second point in the movement path.
