Monitoring tool wear and tool load

Application

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.

Basic AFC settings in AFC.tab

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.
