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
19
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
19
and in the
PLANE SPATIAL
function.
You can select the desired positioning behavior.

behavior of the PLANE function", page 606
