monster cnc router

[collegian]

The company I work for manufacturers 9' x 24' sips (structured insulated panels) for the housing industry. I want to build a 10' x 24' table and route out the windows, doors etc and be able to cut the roof panels. The roof panels are comprised of 7/16 osb board, 10" of foam and 7/16 osb board. To cut the roof panels I would need to make cuts of 34-45 degrees.

How do I get started on the proper parts etc. Everything I read conflicts with everything else I read.

Call me crazy.

First thing you need to do is figure out how to route through an 11" panel.

Going through the 7/16 osb should be easy as one pass. The next 10" is styrofoam, like a coffee cup and the last 7/16 is the osb. I am hopeful that with the proper speed, z axis and number of passes that it should be possible. All part of the monster cnc router I guess. I am hoping that I can do something constructive or positive until the housing industry gets better.

First, you need to find a router bit with a 12" cutting length. Then, you need to figure out how to spin it at least 10,000 rpm without it whipping around like a noodle.

I've seen one online as a video, It looked like a burr rather than a router bit it used.....It had a huge Z axis and made some huge display boots...Not much help but heres the video

Looks like Shopbot already built a cnc for Sips, ( Link ).

That spindle will set you back some $$.

But that panel in the video appears to be about 6" thick, which is a lot different than 11".

I wasn't suggesting that he buy the shopbot table.

Just use the info/video for ideas.

I'm just saying that I don't think you can cut an 11" panel with a router.

I think two different type machines built into one might work better. Have a sawmill type bandsaw on one side that cuts multiple angles. Windows and other cutouts could be done with an upper and lower spindle. If you knew at what height all window cutouts would be, that wouldn't be too difficult.


To use a standard router system with flat table, you would likely need a bit that would be 16" to 18" long for the angle cuts. The spindle would have to be a forth axis to tilt as well.
This would really have to be a monster machine and be out of the router realm. You are probably talking about a $50,000 spindle alone and special made tooling as well.

It would be a cool machine though.

I think it could be done with a real spindle, & a Z-axis that will clear the part.

The key would be to not skimp on the spindle & bit, buy the best with some real power.

14 inch Z-axis travel

Someone call & see how much they want.
