Grind angle formula?

[killingerBlades]

Is there a math formula you can use to figure the angle to grind your blades?

Here is an older thread i found that will give you some food for thought or flat grinding. :3: Now if you are hollow grinding? You will need another formula that I know exists. I just hardly ever hollow grind.
