High-speed Cutting
(Available
only when expansion CPU option is provided)
$
Conventional
high-speed cutting was
such that the host
computer
decoded
the
part
program
and converted it into
binary data to
enable the NC
equipment
to
move
at high speed,
and in
this
way
DNC
operation was
performed via
a
communications module. For the
i80M,
the
part program
stored in
part
program memory
is
converted into
binary data
at high speed.
making it possible
to
execute
the
program
at
high speed.

Conversion mode
Although there
is
an operation
mode in which linear
interpolation
(GOD
blocks in
part
program memory
are converted
into
movement
quantities per
unit time
(hereafter
called
segment
data),
the following
three modes
are provided
for conversion modes.
( i )
Non-conversion mode
Same as in normal
operation.
The
part
program
is decoded block
by
block
as the
machine is
operated.
