This feature allows movements to be rotated about the G92 point in the program. This
feature can be used when the part is setup differently than the way it was programmed.
The example below shows how to rotate the program 90 Degrees about the G92 point.
G26 RA90. (turn rotate on and rotation angle of 90 degrees)
G90 (absolute mode)
G92X0Y0 (start point location)
(the rest of the program here)
G27 (cancel rotation)
M02 (end of program)

If you have other wire EDM equipment (other than Sodick), this feature will allow you to
make the Sodick machine respond to commands that are used in your other machines.
You can think of the string file as a translation table. It lets the Sodick machine read and
execute commands that it would not normally recognize. It can also convert single codes
to mean more than one code.
Other machines may use an M86 command to turn on flushing. Your Sodick machine has
no use for the M86 and normally it would generate an alarm if an M86 were read. On the
Sodick machine, you could use the string file to tell the machine that whenever it reads an
M86, to perform the equivalent function which is T85 (flushing on for Sodick.)
There are some limitations to what the string file can do. For example, some machines
utilize the I and J for circular movements in a totally different way than Sodick. On some
machines, the I and J are the actual absolute positions of the center of a radius, instead of
the incremental distance from the start point of the radius to the center. In this case,
nothing could be done to make the program files from the other machine compatible with
the Sodick control. The string file is stored on the user floppy disk or on the hard drive
and it can be loaded into memory and in the edit screen, you can view and change its
contents.
NOTE: The control uses the string file which is stored on the hard drive or floppy drive,
not the one in memory. If you have to change the string file, change it in the edit screen,
and then be sure to save the file back to the user disk or the hard drive for the changes to
take effect. (See next page for an example of the format and some recommended
settings).
