CNC
Router Packages for 3-Dimensional Machining Applications
Five-axis CNC routers have become the accepted method for production
trimming of thermoformed, composite and fiberglass parts and are being
increasingly used to machine patterns and molds directly from CAD data.
Thermwood is the industry leader in these applications with more five-axis
systems in operation than any other company.
With Thermwood 5 axis CNC router packages you can:
- Trim formed parts or machine patterns or molds using full five-axis
simultaneous motions.
- Execute extremely large CAD generated programs at high speed without
pausing.
- Create three-dimensional programs directly from hand made models
using a Hand Held Programmer and/or a Programming Probe.
One reason for our success is that Thermwood offers features and capabilities
not available from anyone else, and these features are important to your
success. Thermwood is the oldest manufacturer of CNC routers and has
consistently been the technical leader with more US patents on CNC router
technology than all other CNC router companies in the world, combined.
A
highly advanced CNC control – your
key to success
Your CNC router is only as flexible
as your CNC control. Thermwood is the only major CNC router manufacturer
that designs and builds its own CNC control, a control so advanced
it is used by aerospace, defense and even NASA for some of their
most demanding applications. This control is designed from its
very core to operate a CNC router, which means you can do more and
it’s
easier.
Thermwood’s CNC control offers full five axis
simultaneous motion which allows for more efficient program motions.
The system is equipped with five-axis tool length compensation and
individual compensation for each gantry axis of a moving gantry configuration
machine.
There is another important consideration when machining three dimensional
patterns or molds. CAD generated programs usually consist of millions
of tiny motions, all strung together. When these are sent to most CNC
controls, they choke on them. There are two reasons for this.
Most commercial controls have limited program memory, memory that is
too small for typical pattern programs. They rely on a separate PC to
feed pieces of the program to the control as needed. However, because
these tiny motions are executed so fast, it is common to run out of program
code before the PC can supply the next segment, so the machine stops.
It stops and waits until the buffer is refilled and then starts again.
This of course slows you down, but depending on the material, dwelling
on the part can cause burns or other problems.
The second problem with commercial controls is called block processing
time. This is the amount of time required to process a single block of
data. This is important because the block processing time determines
how fast the tiny motion supplied by the CAD system can be run. Slow
block processing times means that the actual program runs slower, sometimes
much slower.
Thermwood’s control is on the leading edge
in both of these areas. First, it has huge program storage capacity
and uses the hard disk as virtual memory. We can easily hold programs
tens of gigabytes in size and execute them with no delays, no stopping.
Thermwood’s control also has one of the fastest,
if not the fastest block processing time in the industry. We can execute
complex CAD generated programs at high speed, and without stopping.
Although these sound like obscure technical issues, they are quite important
to you on any five-axis system you buy. They determine how easy the system
is to use and productive it will be and in some cases, what it can and
cannot do.
The control keeps track of machine use and alerts you when lubrication
or maintenance is needed. It shows you step by step videos of how to
adjust, maintain and repair your machine.
And, because Thermwood controls all the technology, you have single
source responsibility. No longer must you tolerate the machine builder
and control manufacturer blaming each other when you have a problem.
Thermwood stands behind and supports the entire system.
And when new technology comes out, you can easily upgrade your Thermwood
control, we do it all the time. This is seldom possible with others.
The key to CNC router capability is the CNC control, and Thermwood clearly
has the most capable CNC control.
Programming a Five Axis Machine
Creating CNC programs for five-axis trimming
can be challenging, especially when CAD data is not available for a part.
In these instances, Thermwood offers a powerful Hand Held Programmer
which you can use, right on the machine, to trace the part and create
the program. You can create lines, arcs, circles and even splines, quickly
and easily, and this method of creating programs has been refined over
the years to include many programming tools that make the process quicker
and easier.
The Hand Held Programmer is easy to use
and intuitive, so virtually anyone can learn to develop programs with
it. Others may offer a programming box, but there in nothing today that
compares to Thermwood’s Hand Held Programmer.
If you have complex curves, another approach
available from Thermwood is a Programming Probe. This is a probe that
is attached to the spindle, and is used to guide the head around to create
the program. You simply move the probe tip by hand and the machine follows.
Trace a trimmed part and the program is complete. You can use the Programming
Probe and the Hand Held Programmer at the same time to make the job even
easier.
If CAD data is available for your part,
it can be used to generate the trimming program. We can execute programs
generated by your existing CAD/CAM system, or Thermwood can supply full
five-axis CAD/CAM systems capable of designing your part and creating
the trimming program. This same system can also create programs for the
models or molds for your part. The models and molds can be machined on
your Thermwood system and as we stated earlier, huge program capacity
and fast block processing speeds means the most efficient program execution
possible.
Whether executing complex CAD generated
programs or developing programs right at the machine from hand made models,
Thermwood’s systems excel.

Prove your application
BEFORE you buy
 |
Demonstration
Lab fully staffed to insure that we can do your job. |
It is dangerous to take anyone’s
word they can do your job. The only way to know for sure
is to see your job being done. Watch the cycle, see the
result and then you truly know.
Thermwood operates a well
equipped, fully staffed demonstration lab whose purpose
is to demonstrate to both you and us, that we can do your
job and that you will be completely satisfied. We set up,
program and run your parts, with no obligation to you,
to prove out the application before we receive, or accept,
a commitment.
You are invited to our Southern
Indiana facility to see this process in person and discuss
your needs in a friendly, easy and open environment. We
also have the ability to broadcast these demonstrations
live over the web, although if your job is truly custom,
a personal visit is highly recommended. Most people that
visit say they leave with a wealth of information beyond
seeing their parts run. After all, we have been doing this
longer than anyone else and are happy to share this experience
with you.
With this approach, you know
and we know it will work well. This is the only way to
be sure you will be a completely satisfied customer, after
all, you being satisfied is important to us because a large
part of our business is repeat orders from satisfied customers. |

Impact Resistant Head – A Thermwood
Exclusive
There is one potential problem that occurs during programming and setup
of five axis machines. At some time or another you will run the head
into the fixture, in short, a crash. Maintaining accurate alignment of
the axis 4 and 5 head is important, and this type of impact can knock
the head out of alignment.
Thermwood’s head allows for realignment. Some others have no provision
for adjustment, so once you are out of alignment, you’re out of
luck. In the past, a crash often meant you had to realign the head before
you could continue. Today, Thermwood offers an impact resistant head,
which all but eliminates this problem.
On Thermwood’s machines, the axis four and
five mechanism is held accurately in place on precision tapered die
seats with a series of heavy duty die springs. An impact simply compresses
the springs, allowing the head to move off the seats before enough
force is generated to cause damage or affect alignment. This also instantly
stops the machine. Move away from the part and the head returns to
the original position on the die seats and you are ready to continue
with no permanent damage and, seldom, if ever, a requirement for realignment.
The impact resistant head is another feature only available from Thermwood.
Regardless of how you develop your programs or how careful you are, some
time or another, you will crash the head. How the machine handles this
is the difference between a minor inconvenience and perhaps days or weeks
of downtime while the head is re-machined or replaced.
