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:
U
Place the input box at the position in the block where you want to 
insert a position value.
U
Select the actual-position-capture function. In the
soft-key row the TNC displays the axes whose 
positions can be transferred.
U
Select the 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.
