Computer Numerical
Controlled Router...
Thats Gary Pacy of OutBack
Marine showing off their router and showing what it can do.
They do instrument panels and other goodies for the production
boat trade and custom craft.
The panels are so clean in manufacture they appear to be a fine
injection moulding rather than cut from solid stock. The table
part that looks like an Air Hocky table (remember those) allows
objects up to 4X8 foot (1200X2400mm) to lie flat. The deck above
it slides the length of the table and the cutting head traverses
the width, enabling any point on the table to be operated on.
Various rotating cutting bits can be mounted depending on material
and cutting size or shape. The computer program is done conventionally
on a remote machine or supplied by the client. The program I
saw Gary using was very similar to what this paper is produced
on.
The pattern is then sent via cable to the machine and it sends
the deck around the machine with very close tolerance. Thus an
image on a computer screen can be manifested in hard material
in seconds. The big tube above the machine is dust extraction.
These little gems go for from say.. $15,000 second hand for a
basic machine to over $100K for one like Garys shown here.
This machine can turn
any boat building material into a "kit"!
Plywood? No problem. It can cut the ply
to shape as accurate as your supplied dimensions. Any laminated
panel can be cut ready for mounting. Unlaminanted panels like
polycore or foam? No problem. Mount a drawing toll on the head
instead of a cutting tool. Your boats panels are lofted in a
couple hours, as fast as the machine operator can feed them in.
Then it's a matter of cutting with your box knife. Builders I
observed trimed outside the marked lines a little then trimmed
to exact measure after laminating but while the resin was still
green enough to be easy cutting.
See how this router has aided in the construction
of a new design of production boat.
The important thing is to choose your materials
on their merits, not on who seems to have the market for kit
cutting cornered... if your designer refuses to supply the cad
drawings to an independent CNC router operator.. maybe it's because
there are hidden commisions at play. |
