Title:
PRESS SYSTEM AND CONTROL METHOD FOR PRESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/174933
Kind Code:
A1
Abstract:
A press system is provided with: a detection unit (42) that detects the press load when pressing a workpiece; a reference waveform generation unit (43) that generates a reference waveform for comparison on the basis of the load waveform of the press load detected by the detection unit; and a determination unit (44) that determines whether a press abnormality is present on the basis of the reference waveform and the load waveform of the press load detected by the detection unit. As a result of the press system generating a reference waveform, it is possible to determine the state of press working by a simple method.
