Tool compensation with compensation tables

Application

With the compensation table, you can save compensations in the tool coordinate system (T-CS) or in the working plane coordinate system (WPL-CS). You can call the saved compensations during the NC program, in order to compensate for tool values.

The compensation tables offer the following benefits:

  • Values can be changed without adapting the NC program
  • Values can be changed during NC program run

Via the file name extension, you can determine in which coordinate system the control will perform the compensation.

The control provides the following compensation tables:

  • tco (tool correction): Compensation in the tool coordinate system (T-CS)
  • wco (workpiece correction): Compensation in the working plane coordinate system (WPL-CS)

Reference systems

Description of function

In order to correct tool values by using the compensation tables, the steps below are needed:

The compensation table values can be edited within the NC program.

Accessing table values

The values in the compensation tables can be edited even while the program is running.

Compensation during program run

Tool compensation in the tool coordinate system T-CS

The compensation table *.tco defines compensation values for the tool in tool coordinate system T-CS.

Tool coordinate system T-CS

The compensation table .tco is the alternative to compensating with DL, DR and DR2 in the Tool Call block. As soon as you have activated a compensation table, the control overwrites the compensation value from the Tool Call block.

Using TOOL CALL to call a tool

If a shift with the *.tco compensation table is active, the control displays it on the Tool tab of the Status workspace.

The Tool tab

Tool compensation in the working plane coordinate system WPL-CS

The values from the compensation tables with the *.wco file name extension are applied as shifts in the working plane coordinate system (WPL-CS).

Working plane coordinate system WPL-CS

If a shift with the *.wco compensation table is active, the control displays it, including the path, on the TRANS tab of the Status workspace.

The TRANS tab

Activating the compensation tables manually

The compensation tables can be activated manually for the Program Run operating mode.

In the Program Run operating mode, the Program settings window contains the Tables area. In this area, a datum table and both compensation tables can be selected in one selection window for running the program.

When activating a table, the control will highlight this table with the status M.

Selecting a compensation table with SEL CORR-TABLE

Application

If you are using compensation tables, then use the SEL CORR-TABLE function to activate the desired compensation table from within the NC program.

Description of function

For the NC program, both a table *.tco and a table *.wco can be selected.

Input

NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.

Change the following contents as needed:

  • Tools
  • Cutting parameters
  • Feed rates
  • Clearance height or safe position
  • Machine-specific positions (e.g., with M91)
  • Paths of program calls

Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.

In addition, test the NC programs using the simulation before the actual program run.

 
Tip

With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.

Activating a compensation value with FUNCTION CORRDATA

Application

The FUNCTION CORRDATA function allows activating a row of the compensation table for the active tool.

Description of function

The activated compensation values are active up to the next tool change or until the end of the NC program.

If you change a value, then this change does not become active until the compensation is called again.

Input
