In the press working, mold wear necessarily occurs, and if it can be detected, there is a big merit. Progress of mold wears leads to manufacture of defective products and damage to molds, resulting in production line stoppage. Therefore, in this study, we propose a method to prevent these problems by using MT method and Isolation Forest, and we detect mold wear using a microphone. Experiment with a press machine showed the possibility of detection of mold wear.
