Artis tool and process monitoring systems capture the condition of the tool throughout the machining process. The systems provide individually adjustable signal limits to detect e.g. wear of the cutting edge and tool fracture. Cutting tools are loaded with heavy forces at the deformation and friction zones. Tool wear often leads to quality problems. But tool breakage can also be the result of wear which in turn can damage follow-on tools, workpieces or spindles. Since machines today often work unattended and 24/7, permanent monitoring of the tool condition is required. When using Artis systems, it is possible to stop the machine in time if a tool breaks in order to avoid further damage to the tool used in the next operation. Additionally, an immediate stop of the machine axis in the event of large tool breakages prevents collisions. Artis monitoring also shows the wear status of a tool so that the worn tool can be sorted out and, if necessary, a twin tool can be used automatically.
