Abstract: An information processing apparatus includes a detection result acquisition unit configured to acquire a detection result of a physical quantity that changes as a movable body moves while being in contact with a subject; an image data acquisition unit configured to acquire image data of the subject; and a display control unit configured to control a display to display likelihood information indicating a likelihood of abnormality of the subject and the image data in association with each other. The likelihood is determined based on the detection result.

Abstract: An information processing apparatus includes a detection result acquisition unit to acquire, for each of processes performed on a plurality of workpieces, a detection result of a physical quantity that changes according to processing applied to a workpiece; an identification information acquisition unit to acquire process identification information identifying one of the processes performed on the same workpiece and workpiece identification information identifying one of the workpieces subjected to the same process; and a display control unit to display, on a display, the process identification information and the workpiece identification information; and display, on the display, abnormality likelihood information indicating likelihood of abnormality, determined based on the detection result, of the particular process or the particular workpiece, in association with at least one of the process identification information and the workpiece identification information.

Abstract: A diagnostic system includes a tool to perform machining on a workpiece, a test piece to be subjected to test machining by the tool for abnormal detection, a sensor to generate sensor data representing a physical quantity generated in the test machining, and circuitry. The test piece is different from the workpiece. The circuitry controls the tool to perform the test machining in each cycle of machining on the workpiece and calculates a degree of abnormality from the sensor data of the test machining. The test machining is performed on the test piece under a test machining condition corresponding to a machining condition of the machining on the workpiece.
