Cadfil-lite

Cadfil-Lite offers many of the advantages of the more powerful CADFIL-Axsym package with quick and
simple parametric programming for the more common filament winding geometries. Much of the powerful
3D graphics and visualisation are the same as with CADFIL-Axsym. Program creation is via the Cadfil
QuickCad user interface.

Wind programs can be created for:

Helical Winding on cylindrical parts, e.g. pipes, drive shafts
Hoop winding and multi-stage hoop winding on cylinders parts
Helical geodesic winding on cylinders with dome ends
Helical geodesic winding on cylinders with cone ends
Joining paths on Cylinders (pipes).

Lite is a lower-cost entry level for the Cadfil System

All Cadfil software operates on standard PC hardware using Windows 95 or above.

The Mandrel Geometry and winding machine clearance envelope can be quickly entered as a series of
data parameters.The diagram above shows the data parameters for the dome ended vessel
software.The clearance envelope allows close control whilst preventing machine collision with the
mandrel.

Having entered the data
parameters the software
automatically creates the mandrel
geometry and the trajectory across
the surface of the mandrel

The software calculates the number
of circuits required to cover the
mandrel based on material
parameters such as the fibre band
width required.

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).

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.

The machine positions can be
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.
