Got a job - how to do it ? :)

Wouldn't the required tip size will be determined by how sharp the internal corners need to be at the upper surface of the part?

[Boyan Silyavski]

Depends what he is doing exactly. But the corner sharpness itself is determined by the angle. The tip size could determine bottom corner sharpness if any. Once you enter the details you could easily spot in the simulation the difference if any, and time difference

That is geometrically incorrect, if you were right a 15 degree cutter with a 3mm flat will generate really sharp corners?
The size of the flat at the tip of the cutter determines it's effective minimum diameter and directly dictates how sharp an internal corner you can generate with it.

I agree, what i was thinking

[Davek0974]

Yes, it's all supposition at present.

I did look at some scrap blocks today and it seems anything around what appears to be from a 0.2 to 0.4mm radius is a 'sharp' corner for this stuff so a flat tipped v-bit with a 0.1 or 0.2 tip might work, might even be worth trying some of the 3mm engraving cutters i was gifted on it.
