Brief instruction 808D Milling
Basic Theory
G87 Boring cycle Ⅰ / reverse boring
cycle Ⅱ
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

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