FILLETS
bone fillet rounds out the corner, while the T-
bone pulls the circle out to the side of the
vertex.
Dogbone fillet Intersect the circle’s radius, R,
with the inside angle’s vertex and its diameter,
Ø, with the part edges, as shown in Figure 2-7.
T-bone fillet Align the circle’s diameter, Ø,
with the inside angle’s vertex along one side of
the part, as shown in Figure 2-8.
Integrate the circle into the part lines. As
shown in Figure 2-7 and Figure 2-8, draw a
stroke, create a line, or use a Boolean operation
to assimilate the circle into the overall part.
Ensure that the lines are connected.
If you use a different size end mill, you’ll need
to adjust your fillet size to match.
Sketching Sniglets
A sniglet is created using two adjacent circles.
Like dogbones and T-bones, the diameter of
each circle is 110% of the tool diameter. One
core difference—other than the use of two cir-
cles to guide the sniglet creation lines—is that
they are placed on the outside edge of the inte-
rior corner.
Draw two adjacent circles, each circle’s diame-
ter is 110% of the tool diameter. Align the cir-
cles to the top right of the corner vertex.
Incorporate one circle into the part. The circle
directly above the corner vertex will become
the fillet, while the second circle is merely a
guide. Using Figure 2-9 for reference, integrate
the first circle into the overall part.
