Actual Position Capture - HEIDENHAIN TNC 620 User Manual

3

Actual position capture

The control enables you to transfer the current tool position into the
NC program, for example during
Positioning-block programming
Cycle programming
To transfer the correct position values:
Place the input box at the position in the NC block where you
want to insert a position value
Select the actual-position-capture function
In the soft-key row the control displays the axes
whose positions can be transferred.
Select the axis
The control writes the current position of the
selected axis into the active input box.
In the working plane the control always captures the
coordinates of the tool center, even though tool radius
compensation is active.
The control takes the active tool length compensation
into account and always captures the coordinate of the
tool tip in the tool axis.
The control keeps the soft-key row for axis selection
active until the actual position capture key is pressed
again. This behavior remains in effect even if you save
the current NC block or open a new NC block with a path
function key. If you have to choose an input alternative
via soft key (e.g. for radius compensation), then the
control closes the soft-key row for axis selection.
The Actual position capture function is not permitted
when the Tilt working plane function is active.
