General description

By licencing the app TS-PM, a ToolScope can be extended with a monitoring procedure with self-learning limits.

The app is primarily useful for

  • tool breakage monitoring
  • check for correct work piece clamping
  • in General: creating a "sensor footprint" of a process and checking against that footprint in a later mass production


The following figure shows a typical monitoring view demonstrating the monitored sensor signals (red) and limit values (green) during a process. If the red actual value curve breaks through one of the green limit value curves, a corresponding alarm is issued.


Standard tolerance range view, with enabled wear monitoring in the lower window (TS-Wear)


When you press the "Monitor less closely" softkey, the distance between the tolerance ranges and the signal is increased. When you press the "Monitor more closely" softkey, the distance between the tolerance ranges and the signal is reduced.

After an alarm has been triggered, a choice appears, whether this was a correct or a false alarm. If you choose "False alarm", you get several options to react on this event.

By pressing on "Configuration", you will return to the configuration view. This is shown in Figure 19.


Configuration view for the fixed monitoring procedure

In the configuration view, you can select a trigger and up to three monitoring variables in the left-hand area. The "Trigger" channel describes the signal upon whose occurrence the monitoring will be activated (flank change from 0 to 1). The "Monitored signal 1" channel describes the signal with which the process is to be monitored.

Monitoring improves through the provision of additional signals, which the monitoring can evaluate. Depending on the process currently running in the machine, it can select the most meaningful signal from a wide range of signals made available to it. These additional signals can be selected under the "Monitored signal 2" and "Monitored signal 3" channels.

In the right-hand area, use the "Process selection" field to select the process whose settings are to be displayed. Below this, the monitoring parameters for the respective process are displayed.

The "Sensor data" display shows the green limit curve. The signals on which the limit calculation is based (learning data) are drawn in red.

Depending on which of the five monitoring procedures (Fully automatic, Statistical, Fixed, Dynamic or Six Sigma) is selected in the "Limit calculation" selection field, the parameters that you can adapt will change.
