>>> In my experience, I have worked on projects that involve using cutters as small as 0.4mm ball noses, for production runs of 2,400-off components.

Wowee that's impressive,

Do you have any ballparks of where the cost hikes as the cutters get small (4mm?, 1mm?) or is just it a gradual thing?

Do you have a similar sense of when the feature size dictates you move to edm?

Thanks, Alan
