- The control uses process monitoring to detect disturbances in the machining process, e.g:.
- Tool breakage
- Incorrect or missing workpiece pre-machining
- Changed position or size of the workpiece blank
- Wrong material, e.g. aluminum instead of steel
Process monitoring allows you to monitor the machining process during program run using monitoring tasks. The monitoring task compares the signal curve of the current execution of an NC program with one or more reference machining operations. The monitoring task uses these reference machining operations to determine an upper and lower limit. If the current machining operation is outside the limits for a predefined hold time, the monitoring task executes a defined response. If, for example, the spindle current drops due to a tool breakage, the monitoring task executes a predefined response.

- If you are using process monitoring, the following steps are required:
- Defining monitoring sections in the NC program
- Slowly running-in the NC program in Single Block mode before activating process monitoring
- Activating process monitoring
- Running the NC program in Full Sequence
- If necessary, configuring settings for the monitoring tasks
- Selecting a strategy template
- Adding or removing monitoring tasks
- Defining settings and responses within the monitoring tasks
- Displaying monitoring task in the simulation as a process heat map
- Running the NC program again in Full Sequence operating mode
- Selecting other references and optimizing parameters
