Application supplement for LATHE

This supplementary chapter of the manual is only valid for the setting
of

DRO TYPE = LATHE

in the

SETUP

menu.

This is an supplementary chapter to the normal operation manual, it
gives more realistic operational examples for the DRO operation for
LATHE application.
