Ask for help in calculating the cutting size of the spherical crown head
Thread Content
Dear heroes, can you help me solve the formula for calculating the cutting size of the spherical crown head? Thank you very much?
There should be no need to ask for help...
The coefficient is slightly smaller than that of the ellipse, about 1.15~1.2, or you can use the 25198 area to infer,

This is generally determined by the head manufacturer to determine the blank blank size.
This is quite special. Different manufacturers and different head size forming processes require different cutting sizes. It is best to determine the head processing manufacturer first, and the specific head size will be determined by the manufacturer.
