Vibration avoidance is a monitoring method that can change the cutting parameters when vibrations occur.
In this operating mode the ToolScope detects when a sensor signal exceeds a predetermined limit. If longer than a predetermined period of time, it may set the override value to an alternate value at which lower oscillations occur. If the monitored signal (usually a vibration) has fallen back to a normal level after a minimum holding time, the override value is restored to the original level.
When learning, in particular a "switching threshold" is determined. If the monitored signal exceeds this threshold, the ToolScope assumes that there is a vibration.
1.1 Operation of idle detection
As shown oscillation avoidance shows the monitored sensor signal (red, top), the switch-over threshold (green, top), and the override value (red, bottom).

Oscillation avoidance configuration
The configuration view mainly differs from the control view in that a switch-over threshold can be defined, at which you can switch between two override values.
1.2 Configurable parameters
In the left-hand area you can use the drop-down menus in the "Sensor selection" area to select a trigger and a control value. The "Trigger" channel describes the signal upon whose occurrence the monitoring will be activated (flank change from 0 to 1). The "Controlled signal" channel describes the signal to be monitored.
In the right-hand area, use the "Process selection" field to select the process whose settings are to be displayed. Below this, the individual parameters of the respective process are displayed.
The following parameters can be changed manually:
