Ragged edges

maybe you could add your speed and feed so the correct feed could be worked out

Were you using an end mill ? for wood you should be using a router cutter

That ply you used is known as far eastern, and those splinters look normal for that stuff from B & Q ?

The best material would be Birch ply

I think the issue is ply quality. I use to work for print finishers. They have been using cutting forms (steel shaped blades embedded in ply). This ply was real stuff and I don't think It would give so uneven edge.
