Common programming structures:
G87 X—Y—Z—R—Q—P—F—L
Motion process：
① Drilling motion (-Z) →cutting feed
② Motion at the bottom of the hole →
spindle stops
③ Retraction motion (+Z) → manual
operation or fast feed

Make the necessary changes to the ISO programs.
Programs in ISO mode in the 808D have their own rules.
Suitable changes must be made at the appropriate posi-
tions so that you can run the ISO programs!

operation
Step 1
The ISO mode function provided by
the 808D can easily operate the exist-
ing ISO program!
A specified ISO program is then stored in the 808D system and can be
edited and executed as described above.
Transfer ISO files in USB device to 808D.
Press the “NC” SK on the PPU.
Press the “USB” SK on the PPU.
Press the “Copy” SK on the PPU.
Press the “Paste” SK on the PPU.
Connect the USB device with the stored target programs to the USB
interface on the PPU.
Step 2
Use the “Cursor + Select” keys to select the required program
which is then highlighted.
