Selecting data from similar, previously defined
units
After you have started a new unit, you can use the SELECT UNIT DATA
soft key to transfer all data from a previously defined, similar unit.
smarT.NC then uses all values defined in this unit and enters them into
the active unit.
Particularly in the milling units, this makes it very easy to define roughing/
finishing operations by, for example, merely correcting the oversize and,
if required, the tool in the new unit after transferring the data.
smarT.NC first searches the smarT program for a similar unit
from the current block to the top of the program.
If smarT.NC cannot find any corresponding unit up to the
beginning of the program, then it continues searching from
the program end to the current block.
If no corresponding unit is found in the entire program, the
control displays an error message.
