Has anyone found a bit that will cut a smooth edge on corrugated cardboard (the paper stuff, not the plastic stuff)? What cutting sped works best? I have tried a 1/4" dia straight bit, but it produes a bit of a ragged edge.

Don, does a little sanding help. May I ask why your cutting cardboard?

Don,
If it's not too thick maybe an attachment like the "vinyl mate" blade would help you. There are links to the tool on this Forum if you do a search...

Jay, Don's profile says it all "short run packaging components"

I did a few prototype boxes on the bot myself. Same results, fuzzy edges.

Here's a supplier for $299:
There is a 60 degree blade that looks like it would do the job as it is made for thicker material.

Scott,

Didn't see that.. very interesting! Wouldn't a down spiral work pretty nice?

I have seen some pretty thick cardboard stock.

I see a Shopbot as a CNC tool mover. The more tool heads there are, the more opportunities their are for botters. Wouldn't it be great if their was a cutting/creasing head like one of these at a price botters could afford.

That's what I'm after. I've already talked to Gordon about the scoring head. It requires a stepper motor on a second z axis to turn a pizza cutter type wheel into the direction of travel before the axis moves. This will also require a software post-processor to calculate the angle of movement. I would prefer to use router bits to do the cutting, but I could also mount a cutawl if worse comes to worst. I'm hoping to get funding for the project in our 2006 capital budget.
