Sniglet
AtFAB’s version of a dogbone, which removes
the radius left by a 90-degree interior cut. The
sniglet is fully integrated to the cut profile tool-
path.
Speeds
The rotational speed of the router spindle,
measured in revolutions per minute (RPM).
Spindle
The engine that generates the rotation of a cut-
ting tool. In contrast to a spindle, some CNC
routers have an actual router head that does
the cutting.
Stock
The material being milled, and its extents and
properties that are defined in the toolpathing
software.
Structures
Assemblies that efficiently utilize flat material to
resist vertical, gravity loads and sideways, lat-
eral forces. AtFAB designs employ Shear, Tor-
sion, Vierendeel, and Rotational structures to
resist loads of forces.
part to secure the part during routing. Tab
parameters can be set when prescribing tool-
paths in the toolpathing software.
Third Industrial Revolution
Similar to the industrial revolutions that pre-
ceded it, the third industrial revolution brings a
fundamental economic shift. As decentralized,
networked digital manufacturing combines with
new communication technologies, logistical
ecologies, and renewable energy to bring
change to society and culture.
Three-axis
Movement along the x, y, and z axes, within a
work zone.
Toolpath
The feeds, speeds, passes, plunges, as well as
coordinates of cutting, that are CAM software
adds to your cut file’s vectors. CAM software
typically communicates toolpath information to
CNC routers with G-Code.
Toolpathing software
A term for computer-aided manufacturing
(CAM) software.
T-bone
Similar to the dogbone, a T-bone removes the
radius left by a 90-degree interior toolpath with
a 1/2 circle. While a dogbone is a 3/4 circle that
is usually cut as a hole, a T-bone’s 1/2 circle
may be drawn as integral to the profile-cutting
toolpath.
Tabs
An interruption in a profile cut that leaves an
amount of material between the stock and the
Vector
Line with magnitude and direction. It’s the infor-
mation from which the direction of the toolpath
is derived.
Workflow
Your entire process that works across a variety
of collaborators, software, and machines from
design through prototyping and fabrication, fin-
ishing, and assembly.
