Abstract (en)
[origin: WO2015082542A1] The invention relates to a method for monitoring a machining tool which is used for machining primarily metal materials, having a cutting tool, wherein the cutting force, the feed force and the passive force during machining are set, and having sensors for measuring forces. In order that machining can be stopped 2 to 60 seconds, preferably 2 to 10 seconds, prior to failure of the cutting body, the invention proposes that the sensors continuously sense at least one of said forces during machining and machining is stopped if a sudden reduction in the sensed force occurs.
