| Term | Description [ EN / PL ] |
|---|---|
| NAND GATE | A
component
which
implements
the
NAND
function. |
| NAND | A
combination
of
the
Boolean
logic
functions
NOT
and
AND. |
| NANOSECOND | One
thousandth
of
one
microsecond |
| NC STATEMENT | Non-macro statement block that directly controls the CNC. |
| NECKING | Machining a groove or undercut in a shaft
to permit mating parts to be screwed tightly against a
shoulder or to provide clearance for the edge of a
grinding wheel. |
| NEGATIVE LOGIC | Logic
in
which
the
micro
negative
voltage
represents
the
one
(1)
state;
the
less
negative
voltage
represents
the
zero
(0)
state |
| NEMA ENCLOSURES | NEMA is the National Electronic Manufacturers Association, the organization that sets the standards for the enclosures housing CNC electronics. |
| NIBBLING | Punching performed by running the press continuously and repetitively. |
| NICKEL | An alloying element which increases the
strength, toughness, and wear and corrosion resistance
of steels. |
| NITRATING | A case hardening process in which
ammonia or some other form of nitrogen is
introduced to the surface of certain alloys. |
| NIXIE
LIGHT OR TUBE | A
glow
lamp
which
converts
a
combination
of
electrical
impulses
into
a
visible
number |
| NOISE | An
extraneous
signal
in
an
electrical
circuit
capable
of
interfering
with
the
desired
signal. Loosely,
any
disturbance
tending
to
interfere
with the
normal
operation
of
a
device
or
system |
| NONFERROUS | Metal containing no iron, such as brass
and aluminum. |
| NONLINEAR INTERPOLATION TYPE POSITIONING | Positioning individual axes independently. |
| NOR GATE | A
component
which
implements
the
NOR
function |
| NORMAL DIRECTION CONTROL | Controlling a rotary axis so that the tool is oriented in a direction normal to that
of its forward motion. |
| NORMAL OPERATION | Operation in which the movements of the master and slave axes are specified
using separate axis addresses. This is equivalent to normal CNC operation
and is used to machine workpieces on different tables independently. |
| NORMALIZING | Process of heating a ferrous metal or
alloy to above its critical temperature and cooling in
still air to room temperature to relieve Internal
stresses. |
| NUMBER OF REGISTERABLE PROGRAM | Number of programs that can be saved to CNC memory. |
| NUMERICAL CONTROL (NC) | A
technique
of
operating
machine
tools
or
similar
equipment,
in
which
motion
is
developed
in
response
to
numerically
coded
commands |
| NUMERICAL DATA | Data
in
which
information
is
expressed
by
a
set
of
numbers
that
can
only
assune
discrete
values |
