Cylindrical Interpolation Programming Restrictions
When the cylindrical interpolation feature is enabled the following
programming restrictions apply:
Work coordinate system offsets (G52, G54--G59, and G92) for the park
and feed axes (Y and Z) will be temporarily cancelled when in G16.1
mode. Offsets for other axes will not be affected
Tool offsets and cutter compensation/TTRC offsets are allowed on the
cylindrical circle plane during cylindrical interpolation programming
Activation of offsets through PAL is disabled
Jog on the fly is disabled
Cylindrical interpolation cannot be activated during part rotation
G88/G89
Integrand circle/arc programming is not permitted during G02/G03
blocks. Only direct radius (R) programming is allowed
Automatic motion to and from home G27, G28, G29, or G30 is not
permitted.
Work coordinate changes and shifts G53, G54-G59, G59.1, G59.2,
G59.3, G50/G92, G52, G92.1 are not permitted
Cavity and Irregular pocket cycles cannot be used
Only the primary spindle (selected via G12.1) may be used in
coordination with cylindrical interpolation. If the system uses Auxiliary
Spindle(s), and the auxiliary spindle is the controlling spindle when
cylindrical interpolation is selected, an error message appears.
If desired, the system installer has the option of controlling selected axes
through the PAL program. When an axis is under PAL control, the
operator and part program have no control on that axis. Jog commands as
well as part program commands are typically ignored unless PAL is written
to manipulate these values in some manner.
Be aware that it is possible to disable axis position displays on the CRT for
an axis under PAL control. Refer to the documentation provided by your
system installer for details on an axis controlled by PAL.
Important: S--Curve Acc/Dec mode is not available with PAL axis Mover.
