Limitation
- Single-block operation
When single-block operation is carried out in the nano smoothing
mode, the operation stops at a corrected insertion point not at a
programmed point.
Even in the nano smoothing mode, normal single-block operation is
carried out for a block that does not satisfy the conditions of nano
smoothing mode.
- Tool length compensation
To carry out tool length compensation, specify the command before
specifying nano smoothing. Avoid changing the amount of
compensation in the nano smoothing mode.
If G43, G44, or G49 is specified in a block between the block in
which the command of nano smoothing mode on (G5.1 Q3) is
specified and the block in which the command of nano smoothing
mode off (G5.1 Q0) is specified, an alarm PS0343 will be issued.
- Cutter or tool nose radius compensation
If cutter or tool nose radius compensation is specified in the nano
smoothing mode, the nano smoothing mode is cancelled. Then,
when the command of cutter or tool nose radius compensation cancel
(G40) is specified, a decision is made whether to start nano smoothing
from the next block. The startup and cancel operations of type C are
always carried out for the cutter or tool nose radius compensation
specified in the nano smoothing mode, irrespective of the parameter
setting.
A command related to cutter or tool nose radius compensation should
not be specified in the nano smoothing mode unless it is absolutely
necessary.
- Interruption type custom macro
No interruption type custom macro can be used in the nano smoothing
mode.
If the nano smoothing mode is specified while an interruption type
custom macro is enabled or if an interruption type custom macro is
enabled in the nano smoothing mode, an alarm PS0342 will be issued.
- Manual intervention
Manual intervention by specifying the manual absolute on command
cannot be performed in the nano smoothing mode. If this is
attempted, an alarm PS0340 will be issued at the cycle start after
manual intervention.
