Not much math. Tie a spring scale (aka "fish scale") to an end mill placed in the chuck and pull sideways, Record the force on the scale and use a dial indicator to measure the deflection of the end mill. Plot a few points. With no math you now know the "spring" in the system. One thing, be sure to measure in both X and Y directions as they are likely different.
With only middle school algebra, you can use the plot to solve for the spring constant (Remember Hook's Law?) But really all you need is the plot. That said, I doubt this matters as most people will make a final light pass that has almost zero side force, so in the end, the "sping" does not matter much. I don't know the true source in in-accuracy in a typical mill. Why are we not able to get to one micrometer?
