Multiple axismachining
12.2 The PLANE function: Tilting the working plane (software option 8)
Effect with a free rotary axis
For the positioning behaviour with the COORD
ROT and TABLE ROT transformation types, it does
not matter if the free rotary axis is in the table or
the head
The resulting axis position of the free rotary axis
depends on an active basic rotation among other
factors
The orientation of the working plane coordinate
system also depends on a programmed rotation,
for example with Cycle 10 ROTATION
Soft key Effect
COORD ROT:
The control positions the free rotary axis to 0
The control aligns the working plane coordinate
system according to the programmed spatial
angle
TABLE ROT with:
SPA
SPC
The control aligns the free rotary axis according
to the programmed spatial angle
The control aligns the working plane coordinate
system according to the basic coordinate
system
TABLE ROT with:
At least
SPC
The control does not position the free rotary
axis. The position before tilting the working
plane is maintained
Because the workpiece was not positioned,
the control aligns the working plane coordinate
system according to the programmed spatial
angle
If no transformation type was specified, the control
uses COORD ROT transformation for the PLANE
functions
