Hi everyone,

I'm glad to find easycomposites.com. I could find almost everything I need for my project. And Now I have a question about how to deal with the edge, didn't find much information about this topic.

I'm building sunglasses and prescription glasses using carbon fiber. My current plan is resin infusion using custom molds and forming curved carbon fiber sheets and then CNC milling the edge. The problem is, after CNC, the edge is squarish and sharp. However, I found that product from other brands such as Oakley Carbon Blade has a smooth and round edge. I looked closely but could not find any fiber structure or texture on the edge. My theory about how to form the round edge is using high speed CNC milling using custom tool head, for example, a curved tool head. So is there anyone has the experience of treating the edge for aesthetic and comfort purposes? How to achieve such an effect.

Thank you

Best regards,
