Formula For Finding Allowance When Step
Depth Is Less Than Cutter Radius

Just a little something we use at work, handy if you need it.

D=Sq Root of [h(2R-H)]
R-D=Allowance To Full Radius Runout

2D= Stepover For A Ballnose Endmill -- Insert Desired Cusp Height (H) For Ballnoseing A Surface, And Radius

PS: Have something to add? A helpful tip for others? E-mail me I just might add it.
