Need advice on fluting a large area

[loopacrylics]

Hello everyone! Hope the holidays treated everyone well this year.

I am stuck on a project and am trying to figure out how to go about this ramp.

I have a 7/8" by 60" area that I need to ramp down over. (Please see photos) I am aiming for no flat spot but the way we currently have it set up it is taking quite a bit of time. Can anyone give me advice on how to set this up properly?

This is how we have it currently set up:

I am aiming for no flat spot ...

With that wall on the left-hand side of the image you'll always have a flat spot as the bottom of the bit is parallel to the table and your bit will be stopping at the wall. If the bit could "go off the edge" you wouldn't get a flat.

Can you fixture the acrylic at the slope that you want and cut this with a simple pocket toolpath?

I agree that a fixture is a better solution.

Flute flat.

Thank you for the advice gentleman. We like the idea of a fixture and are going to try creating one.

Now that I’ve had a bit to think about this: if the slot walls in the sketch above are supposed vertical then angling the material to cut the slot with a pocket toolpath won’t help much unless you cut two pockets first angling the material to the left and another angling it to the right.

If you just cut the pocket you’ll end up two sloping walls.
