With Adaptive Feed Control (AFC), you can monitor the tool for wear and breakage. The AFC-OVLD1 and AFC-OVLD2 columns in the tool management can be used for this.
Description of function
If the AFC.TAB columns FMIN and FMAX each have a value of 100%, Adaptive Feed Control is deactivated, but cut-related tool wear monitoring and tool load monitoring remain active.
Tool wear monitoring
Activate cut-related tool wear monitoring by entering a value not equal to 0 in the AFC-OVLD1 column in the tool table.
The overload response depends on the AFC.TAB column OVLD.
- In conjunction with cut-related tool wear monitoring, the control only evaluates the options M, E, and L in the OVLD column. The following responses are possible:
- Pop-up window
- Lock current tool
- Insert replacement tool
Tool load monitoring
Activate cut-related tool load monitoring (tool breakage control) by entering a value not equal to 0 in the AFC-OVLD2 column in the tool table.
As overload response, the control always executes a machining stop and locks the momentary tool.
In turning mode, the control can check for tool wear and tool breakage.
A tool breakage leads to a sudden load decrease. If you want the control to monitor the load decrease, too, enter the value 1 in the SENS column.
