Multiple-axis machining | The PLANE function: Tilting the working plane (option 8)
Example
The following example shows the effect of the TABLE ROT
transformation type in conjunction with a free rotary axis.
...
6 L B+45 R0 FMAX
Pre-position rotary axis
7 PLANE SPATIAL SPA-90 SPB+20 SPC+0 TURN F5000
TABLE ROT
Tilt the working plane
...
Origin A = 0, B = 45 A = –90, B = 45
The control positions the B axis to the axis angle B+45
With the programmed tilting situation with SPA–90, the B axis
becomes the free rotary axis
The control does not position the free rotary axis. The position of
the B axis prior to the tilting of the working plane is maintained
Since the workpiece was not also positioned, the control orients
the working plane coordinate system in accordance with the
programmed spatial angle SPB+20
Tilting the working plane without rotary axes
Refer to your machine manual.
This function must be enabled and adapted by the
machine manufacturer.
The machine manufacturer must take the precise angle
into account, e.g. the angle of a mounted angle head in
the kinematics description.
You can also orient the programmed working plane perpendicularly
to the tool without defining rotary axes, e.g. when adapting the
working plane for a mounted angle head.
Use the PLANE SPATIAL function and the STAY positioning behavior
to swivel the working plane to the angle specified by the machine
manufacturer.
Example of mounted angle head with permanent tool direction Y:
Example
11 TOOL CALL 5 Z S4500
12 PLANE SPATIAL SPA+0 SPB-90 SPC+0 STAY
The tilt angle must be precisely adapted to the tool angle,
otherwise the control will generate an error message.
