Multiple-Axis Machining | The PLANE function: Tilting the working plane (option 8)
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:
The PLANE function is to automatically position
the rotary axes to the calculated position values.
The position of the tool relative to the workpiece
remains the same.
The control carries out a compensation
movement in the linear axes.
The PLANE function is to automatically position
the rotary axes to the calculated position values,
but only the rotary axes are positioned.
The control does
movement for the linear axes.
You will position the rotary axes later in a
separate positioning block
If you selected the MOVE option (the PLANE function is used to
position the axes automatically), the following two parameters:
Dist. tool tip – center of rot. and Feed rate? F = are still to be
defined.
If you selected the TURN option (the PLANE function is used to
position the axes automatically), the following parameter: Feed
rate? F = is still to be defined.
As an alternative to defining a feed rate F directly by entering a
numerical value, you can also position the axes with FMAX (rapid
traverse) or FAUTO (feed rate from the T block).
If you use PLANE together with STAY, you have to
position the rotary axes in a separate block after the
PLANE function.
