Limitation
- Arc radius specification in the circular interpolation
In the cylindrical interpolation mode, an arc radius cannot be specified
with word address I, J, or K.
- Positioning
In the cylindrical interpolation mode, positioning operations
(including those that produce rapid traverse cycles such as G28, G53,
G73, G74, G76, G80 to G89) cannot be specified. Before
positioning can be specified, the cylindrical interpolation mode must
be cancelled. Cylindrical interpolation (G07.1) cannot be performed in
the positioning mode (G00).
- Cylindrical interpolation mode setting
In the cylindrical interpolation mode, the cylindrical interpolation
mode cannot be reset. The cylindrical interpolation mode must be
cancelled before the cylindrical interpolation mode can be reset.
- Rotary axis
Only one rotary axis can be set for cylindrical interpolation.
Therefore, it is impossible to specify more than one rotary axis in the
G07.1 command.
- Rotary axis roll-over
If a rotary axis using the roll-over function is specified at the start of
the cylindrical interpolation mode, the roll-over function is
automatically disabled in the cylindrical interpolation mode. After the
cylindrical interpolation mode is canceled, the roll-over function is
enabled automatically.
- Rotary axis control function
If a rotary axis using the multiple rotary axis control function is
specified at the start of the cylindrical interpolation mode, the multiple
rotary axis control function is automatically disabled in the cylindrical
interpolation mode. After the cylindrical interpolation mode is
canceled, the multiple rotary axis control function is enabled
automatically.
- Cutter or tool nose radius compensation
If the cylindrical interpolation mode is specified when cutter or tool
nose radius compensation is already being applied, correct
compensation is not performed. Specify compensation in the
cylindrical interpolation mode.
- Canned cycle for drilling
Canned cycles (G73, G74, and G81 to G89 for M series / G80 to G89
for T series) for drilling, cannot be specified during cylindrical
interpolation mode.
