Actual position capture

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

program, for example during

Positioning-block programming

Cycle programming

Tool definition with TOOL DEF

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 the actual-position-capture function: In the soft-

key row the TNC displays the axes whose positions

can be transferred

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.
