HARDNESS

was wondering if maybe it would be useful to add a hardness number box as part of the variables

That creates a lot of problems.
Hardness is not a difinive factor.
Besides I don't really know how to apply hardness nuber to anything really.
There is no hard and fast formula around for that.

If you got suggestions I am listening....

well lets say im machining a2 only ive had it heat treated to 40-45rc (sorry i use c scale)...i was thinking you would have a box next to the material selection in your calc, that you can toggle on and off and then you could apply a number range to your material selection. maybe thats asking too much...im not sure of the formalities of computer programming, nor do i know the formulas you use to achieve everything you have thus far. just an idea i had.

40-45rc is just an example...but sometimes i machine a2 at 60rc, and i was thinking to try cutting into these pins we made from drill blank this week, which is i understand correctly is m1 @70-75 rc...

There is already H13 steels for that.
Look for it. It says H13 40-45 RC and so on.
It comes up to 50-55 rc if I remember correctly.

I promise to update material list with more hard steels next time.
In the future you will have ability to define your own materials.
