NOTE
1 The size of files into which an NC program is divided
should be 20 to 30 MB. If the size is very large, there
will be much idle time before the DNC operation
begins. If the size is very small, data may be
interrupted between files, resulting in a cutter mark
being left on the workpiece.
2 An NC program can be divided in the middle of a
block, but it should be divided between blocks. In
addition, a tool retract operation should be inserted at
the end of each file resulting from NC program
division. Doing so can avoid an interruption of data
between files, therefore preventing a cutter mark.
3 The file list and the files contained in the list must be
stored in the same directory of the same host
computer.
