Datum table

Application

A datum table saves positions on the workpiece. To use a datum table, you must activate it. The datums can be called from within an NC program, for example in order to execute machining processes on several workpieces at the same position. The active row of the datum table serves as the workpiece datum in the NC program.

Description of function

The datums from a datum table are referenced to the current workpiece preset. The coordinate values from datum tables are only effective as absolute coordinate values.

Datum tables can be used in the following situations:

  • Frequent use of the same datum shift
  • Recurring machining sequences on different workpieces
  • Recurring machining sequences at different positions on the workpiece

Activating the datum table manually

A datum table 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.

Activating a datum table in the NC program

To activate a datum table in the NC program:

    1. Select Insert NC function
    2. The control opens the Insert NC function window.

    2. The control opens the action bar.

    1. Select Selection
    2. A file selection window opens.

    Tip

    If you enter the datum table name manually, please note the following:

    • If the datum table is stored in the same directory as the NC program, enter the file name only.
    • If the datum table is not stored in the same directory as the NC program, enter the complete path.
