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 handmade models using a Hand Held Programmer.
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 that 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 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 handmade models, Thermwood’s systems excel.
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.
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.
