| CADFIL®-Axsym A powerful solution for all rotationally symmetric winding |
The CADFIL®-Axsym package can
generate winding programs for all
rotationally symmetric components
including pipes, spheres, gas
bottles, golf shafts, storage tanks…
the possibilities are endless. The
following information briefly
describes the basic stages of
program generation and shows
some of the many features of the
system. Other software options
exist for more complex parts such
as pipe bends, Ts, and elliptical
sections to name but a few of the
options. Cadfil software operates
on standard PC hardware using
Windows 95 or higher

The Mandrel Geometry and winding
machine clearance envelope can
be quickly entered and modified
from a single easy to use dialogue
box. The graphics and text windows
are automatically updated.
Convex and concave arcs can be
fitted between data positions and
edited as required.
The clearance envelope allows
close control whilst preventing
machine collision with the mandrel.
For simple shapes an envelope can
be automatically created.

Mandrel Data Entry
Having created the mandrel geometry
the user can interactively create non-slip
geodesic fibre paths. Non-geodesic
paths can be created using the friction
facilities. In this way the user can control
wind angles and turning diameters.
The 3D geometry and paths can be
viewed from pre-set viewpoints or from
any user-defined viewpoint.
For parts such as gradually tapered
shafts (e.g. golf shafts) the user can
generate constant wind angle
(non-geodesic) paths using the constant
angle option.

Mandrel With Machine envelope
Mandrel With Fibre Path
Having created fibre path with two
turning points the software
calculates the number of circuits
required to cover the mandrel
based on material parameters such
as the fibre band width and the
number and type of rovings to be
used.
Cadfil now has a material database
containing data on many
commerically available rovings
including E-glass, S-Glass , Carbon
and Aramid fibres
A band pattern table is created
(see across) and the user can
select the band structure required. If
required the number of cycles can
be adjusted to give alternative
patterns.
The selected band structure can be
viewed in the 3D viewing system
(see below).
The user is given important data
such as a thickness graph of the
part and the amount of fibre used.
Neutral file interfaces can be
supplied to output data for Finite
Element Software.
Machine positions are calculated
using the envelope and saved to a
data file. All CADFIL data files are
text files and can be viewed if
required.

Pattern Visualisation
The machine positions can
displayed in 3D around the
mandrel or if required the user
can define the machine fibre
dispensing head using brick and
cylinder solid shapes and
perform a full 3D animation
including all machine motions
such as eye roll and eye yaw. An
example of this is shown in the
picture to the left.

Full 6 axis winding
The last stage of program generation is
post-processing where the path is converted to
machine control data. Numerous control options can
be set dependant on the axes available on the
machine. Different speed control options can be set
to reduce winding time or limit axis accelerations. The
software calculates the winding time.
Cadfil is supplied configured for the customers
winding machine. Cadfil can be supplied with multiple
machine configurations so that the user can select
which machine is to be used. Cadfil can be
configured for all filament winding machines types and
control systems from 2 to 6 axes of control.
