Manufacturing monitoring assistance device, manufacturing monitoring assistance method, and manufacturing monitoring assistance program

A manufacturing monitoring assistance method implemented by a manufacturing monitoring assistance device including a memory, an input device, an output device, and a processor communicatively coupled to the memory, the input device, and the output device,

• the manufacturing monitoring assistance method comprising:
• causing the processor to create a computation model in a case where a product as a sample is normal, based on a three-dimensional form acquired from the product,
• wherein the product comprises a plurality of members welded together;
• causing the processor to create a corrective computation model in a case where the product is abnormal, by adding a sample of an abnormal portion in the product to the created computation model, and to perform a simulation on each of the computation model and the corrective computation model;
• and
• causing the processor to determine a method for monitoring a manufacturing process for the product, based on an abnormality index being a difference between an output from a sensor as a result of the simulation performed on the computation model and an output from a sensor as a result of the simulation performed on the corrective computation model, and to cause the output device to display the determined method and the abnormality index,
• wherein the manufacturing process comprises a welding process, and
• wherein the processor accepts entries, by user, of a state of an abnormality in the product, a position of the abnormality in the product, a condition of occurrence of the abnormality, and a degree of importance of the abnormality in association with a sort of the product, and regards the accepted state of the abnormality as the sample of the abnormal portion.

A non-transitory computer-readable storage medium including a manufacturing monitoring assistance program stored therein,

• the manufacturing monitoring assistance program, when executed by one or more processors included in a manufacturing monitoring assistance device, causing the one or more processors to:
• execute processing of creating a computation model in a case where a product as a sample is normal, based on a three-dimensional form acquired from the product,
• wherein the product comprises a plurality of members welded together;
• execute processing of creating a corrective computation model in a case where the product is abnormal, by adding a sample of an abnormal portion in the product to the created computation model, and performing a simulation on each of the computation model and the corrective computation model;
• and
• execute processing of determining a method for monitoring a manufacturing process for the product, based on an abnormality index being a difference between an output from a sensor as a result of the simulation performed on the computation model and an output from a sensor as a result of the simulation performed on the corrective computation model, and causing an output device to display the determined method and the abnormality index,
• wherein the manufacturing process comprises a welding process, and
• wherein the one or more processors accepts entries, by user, of a state of an abnormality in the product, a position of the abnormality in the product, a condition of occurrence of the abnormality, and a degree of importance of the abnormality in association with a sort of the product, and regards the accepted state of the abnormality as the sample of the abnormal portion.
