How To Put A Bevel On The OutSide Of The Acrylic

It would be difficult to put a smooth bevel on the edge with out using a chamfering or vbit to cut the bevel after the parts have been cut. Unless I misunderstand the question. A picture -- or a copy of the .dxf or .svg file -- of what you are trying to make would be easier to visualize the problem you are trying to solve.

 

sometimes it's easier to post process using a router table or even your cnc router with a v-bit and a guide bearing to make a chamfer.. using your cnc router like an inverted router table.

 

That is how I do it, unless the slot or opening is too small.

 

The SVG is only 2kb and has no content and the pic is difficult to tell what it is.
I think you want a round over not a chamfer or "bevel"

I only saw one hole on that svg. no perimeter. For cutting out the profile and holes you need a cutter like this, or smaller if the hole is smaller than 1/4" Upcut Single Flute Solid Carbide End Mill 1/4" Diamond Carbon

To make a bevel, you need a beveled endmill for the CNC, or router bit for a router table. It would also have to be the angle you want. I have a 90 degree endmill just for doing bevels. I run an engraving tool path around the perimeter of all items I want beveled.

You could do it all with a ball nose endmill if you were cutting it like a 3D carve, but it would be VERY time consuming and you need CAM software able to generate the gcode. You would also have to cut fairly deep into the spoil board,

 

It could work, but since it does not come to a fine point, you would need to offset your beveling pass by the diameter of that center part of the bit.
