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.
