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)

Description of function
In order to correct tool values by using the compensation tables, the steps below are needed:
- Creating a compensation table
- Activating the compensation table in the NC program
- As an alternative, activating the compensation table manually for the program run
- Activating a compensation value
The compensation table values can be edited within the NC program.
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.
The compensations have the following effects:
- In the case of milling cutters, as an alternative to the delta values in the TOOL CALL
- In the case of turning tools, as an alternative to FUNCTION TURNDATA CORR-TCS (#50 / #4-03-1)
Compensating turning tools with FUNCTION TURNDATA CORR (#50 / #4-03-1)
- In the case of grinding tools, as compensation for LO and R-OVR (#156 / #4-04-1)
If a shift with the *.tco compensation table is active, the control displays it on the Tool tab of the Status workspace.
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
The *.wco compensation tables are used mainly for turning (#50 / #4-03-1).
The compensations have the following effects:
- For turning operations, as an alternative to FUNCTION TURNDATA CORR-WPL (#50 / #4-03-1)
- An X shift affects the radius
The following options are available for a shift in the WPL-CS:
- FUNCTION TURNDATA CORR-WPL
- FUNCTION CORRDATA WPL
- Shifting with the turning-tool table
- Optional WPL-DX-DIAM column
- Optional WPL-DZ column
The shifts programmed with FUNCTION TURNDATA CORR-WPL and FUNCTION CORRDATA WPL are alternative programming options for the same shift.
A shift in the working plane coordinate system (WPL-CS) defined by the turning-tool table is added to the FUNCTION TURNDATA CORR-WPL and FUNCTION CORRDATA WPL functions.
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.
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.
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.

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.
