A channel or canal surface is a surface produced by the envelope of a family of
spheres whose centers are located on the directrix of a space curve. The canal
surface is known as a pipe surface when the radius of the producing spheres are
constant. The canal surface is called a tube or tubular surface when the radius
function r(t) = r is a constant. Tube surfaces are used to show 3-dimensional
shapes such as pipes, ropes, poles. In addition, tube surfaces are used for modeling solids and surfaces for computer aided geometric design and fabrication.
On the other hand, Galilean geometry is one of the geometries whose motions
are the Galilean transformations of classical kinematics. In this paper, first of
all, we define a new orthogonal frame in G3. Then, we get condition of general
helix in regard to new orthogonal frame in the Galilean 3-space and we obtain
characterizations of tubular surfaces with the new orthogonal frame in G3.
