Provided is an abnormality prediction system and an abnormality prediction method that are capable of predicting an abnormality occurring in a die that is used in a press machine. A die abnormality prediction system (50) includes: an acoustic emission (AE) sensor (62) configured to detect an elastic wave that occurs in a processing portion of a die during processing performed by a press machine using the die; a stamping load detection sensor (61) configured to detect a parameter (a stamping load) other than a parameter regarding the elastic wave, out of parameters regarding a state of the die during the processing performed by the press machine using the die; a score calculation unit (56) configured to calculate an abnormality prediction score of the die based on an output signal from the AE sensor (62) and an output signal from the stamping load detection sensor (61); and an abnormality prediction unit (57) configured to predict an abnormality occurring in the die, based on a result of the calculation performed by the score calculation unit (56).

A die compatibility adaptor including a housing and a die cable extending outward from the housing and terminating at a die cable end engageable with a manufacturing die that includes a first proximity sensor configured to output a first proximity signal and a second proximity sensor configured to output a second proximity signal. The die compatibility adaptor further includes a direct cable receptacle communicatively coupled to the die cable, a duplicate cable receptacle, and one or more isolation relays positioned between and communicatively coupled to the duplicate cable receptacle and the die cable, the one or more isolation relays having a closed position and an open position. In the closed position, the duplicate cable receptacle is communicatively coupled to the die cable.

An imaging system, safety system or combined imaging and safety system includes a light transmitter and a corresponding receiver. Image data relating to a machine tool and/or workpiece is derived and processed to determine information regarding the tool and/or tool position and/or extent of work carried out on the workpiece. A screen, such as a shadow screen, can be used to form an image of a profile of the tool tip and end of the workpiece. Tool tip position and extent of work on the workpiece can be derived from the image. Certain aspects are directed to a safety system application for halting a machine or tool when a light beam is interrupted, and can provide progressive muting of beam interruption detection, such as by systematically disregarding or muting signals from rows of receiver array elements as the beam passes through a mute point ahead of a tool.
