I need to machine some metric trapezoidal threads. Both internal and external.
What's the best way to do that?
Is hand grinding the tools going to be my best approach? I think maybe it is since they are for making molds of two mating parts. The molds can't be of the exact thread forms or the parts won't fit together. A proper cutting tool for those threads might not produce what I need. I'm still thinking my way through the process.
