Method and device for detecting a cut section

摘要

Methods, devices and systems for detecting an incomplete cutting action when cutting a workpiece with a high-energy beam are disclosed. In one aspect, a method includes taking an image of a region of the workpiece to be monitored, the region including an interaction region of the high-energy beam with the workpiece, evaluating the image taken in order to detect pooled slag at an end of the interaction region opposite a cutting front, and detecting whether a related cutting action is incomplete based on an occurrence of detection of pooled slag.
