Multiple-Axis Machining | The PLANE function: Tilting the working plane (option 8)
Comparison of the tilting orders:
Tilting order A-B-C:
1 Tilt about the non-tilted X axis of the workpiece coordinate
system
2 Tilt about the non-tilted Y axis of the workpiece coordinate
system
3 Tilt about the non-tilted Z axis of the workpiece coordinate
system
Tilting order C-B-A:
1 Tilt about the non-tilted Z axis of the workpiece coordinate
system
2 Tilt about the tilted Y axis
3 Tilt about the tilted X axis
Programming notes:
You must always define all three spatial angles SPA,
SPB and SPC, even if one or more have the value 0.
Depending on the machine, Cycle G80 requires
you to enter spatial angles or axis angles. If the
configuration (machine parameter setting) allows
the input of spatial angles, the angle definition is
the same in Cycle G80 and in the PLANE SPATIAL
function.
You can select the desired positioning behavior.

Input parameters
Example
N50 PLANE SPATIAL SPA+27 SPB+0 SPC+45 .....*
Spatial angle A?: Rotational angle SPA about the
(non-tilted) X axis. Input range from -359.9999 to
+359.9999
Spatial angle B?: Rotational angle SPB about the
(non-tilted) Y axis. Input range from -359.9999 to
+359.9999
Spatial angle C?: Rotational angle SPC about the
(non-tilted) Z axis. Input range from -359.9999 to
+359.9999
