Hi Lorraine,
Didn't see any other replies so I thought I'd give you my opinion.
0.05 is, in my opinion, barely achievable in a production environment. You may
or may not be lucky. I would suggest +/-0.10mm is a more realistic tolerance
for routing. If you need better than that then you'll have to buy a punch.
Regards,
