Abstract: A press system includes: a press device configured to perform press working on a workpiece; a detection device configured to detect a press load applied for the press working by the press device; a number acquisition device configured to acquire a number of cycles of press loading, for each section of a plurality of sections into which a press loading region over a total length of a slide stroke is divided; a stress calculation device configured to calculate a stress applied to the press device, the stress corresponding to the press load for each section of the press loading region; and a degree-of-fatigue calculation device configured to calculate a degree of fatigue of the press device, based on respective stresses applied to the press device and respective numbers of cycles of press loading, for the plurality of sections of the press loading region.

Abstract: A press system includes a detection unit configured to detect occurrence of an abnormality during press working for a workpiece, and an abnormality determination unit configured to determine an abnormality level, based on the abnormality detected by the detection unit and a stoppage period for which a pressing operation is stopped after occurrence of the abnormality.

Abstract: A machine system includes: a machine main body configured to process a workpiece, a camera configured to take a video of a processing process in which the workpiece is processed by the machine main body; and an information processing device that includes a memory and is configured to store, in the memory, video data acquired from the video taken by the camera. The information processing device is configured to protect, upon occurrence of abnormality in the processing process, the video data spanning a predetermined set period including a time of occurrence of the abnormality.

Abstract: A press system includes: a detection unit configured to detect a press load applied for pressing a workpiece; a reference waveform generation unit configured to generate a reference waveform for comparison, based on a load waveform of the press load detected by the detection unit; and a determination unit configured to determine whether a press abnormality is present, based on the load waveform of the press load detected by the detection unit and the reference waveform. The press system generates the reference waveform, and therefore, the state of press working can be determined by a simple method.

Abstract: A press system includes: a measurement unit configured to measure a press load applied for pressing a workpiece; a calculation unit configured to calculate a workload based on the press load measured by the measurement unit; a determination unit configured to make a determination about whether the workload calculated by the calculation unit exceeds an allowable value; and a notification unit configured to provide notification of an abnormality based on a result of the determination by the determination unit. Accordingly, in response to pressing with an overload higher than an allowable value, notification of an abnormality can be provided.

Abstract: A press system includes: a detection unit configured to detect a press load applied for pressing a workpiece; a calculation unit configured to calculate an amount of eccentricity of a slide based on the press load detected by the detection unit; a determination unit configured to make a determination about whether the press load detected by the detection unit exceeds an allowable value of press load based on the amount of eccentricity calculated by the calculation unit; and a notification unit configured to provide notification of an abnormality based on a result of the determination by the determination unit. Accordingly, whether an abnormality is present or not is determined using an allowable value of press load based on an amount of eccentricity, and whether an eccentricity abnormality is present or not can thus be determined with high accuracy.
