Automatic positioning:
MOVE/TURN/STAY
(entry is
mandatory)
After you have entered all parameters for the plane definition, you
must specify how the rotary axes will be positioned to the calculated
axis values:
8 The PLANE function is to automatically position the
rotary axes to the calculated position values. The
position of the tool relative to the workpiece is to
remain the same. The TNC carries out a
compensating motion in the linear axes.
8 The PLANE function is to automatically position the
rotary axes to the calculated position values, but only
the rotary axes are positioned. The TNC does not
carry out a compensating motion in the linear axes.
8 You will position the rotary axes later in a separate
positioning block.
If you have selected the MOVE option (PLANE function is to position the
axes automatically), the following two parameters must still be
defined: Dist. tool tip – center of rot. and Feed rate? F=. If you
have selected the TURN option (PLANE function is to position the axes
automatically without any compensating movement), the following
parameter must still be defined: Feed rate? F=. As an alternative to
defining a feed rate F directly by numerical value, you can also position
with FMAX (rapid traverse) or FAUTO (feed rate from the TOOL CALL
block).
If you use PLANE AXIAL together with STAY, you have to
position the rotary axes in a separated block after the
PLANE
function.
