Hi all,

I have the following formula for calculating the “scallop height” (h) with a spherical cutter of radius ®, given the “stepover” (x).

h=r-\sqrt{r^2-(x^2/4})

With my remnants of high-school algebra, I tried to “reverse” the formula to solve for x given a desired h. However, my formula does not give me an accurate result, so I must have done something wrong…

x=\sqrt{8*h*r-h^2}

So, does anyone know how to do this correctly?

TIA, --Mitch
