Actual position capture

The TNC enables you to transfer the current tool position into the

program, for example during

Positioning-block programming
Cycle programming

To transfer the correct position values, proceed as follows:

Place the input box at the position in the block where you want

to insert a position value

Select actual-position capture: In the soft-key row

the TNC displays the axes whose positions can be

transferred
Select an axis: The TNC writes the current position

of the selected axis into the active input box

In the working plane the TNC always captures the

coordinates of the tool center, even though tool

radius compensation is active.
In the tool axis the TNC always captures the

coordinates of the tool tip and thus always takes the

active tool length compensation into account.
The TNC keeps the soft-key row for axis selection

active until you deactivate it by pressing the actual-

position-capture key again. This behavior remains in

effect even if you save the current block and open

a new one with a path function key. If you select a

block element in which you must choose an input

alternative via soft key (e.g. for radius compensation),

then the TNC also closes the soft-key row for axis

selection.
The actual-position-capture function is not allowed if

the tilted working plane function is active.
