Dresser/Wheel Radius Compensation

There is a limit to the amount that an I, K vector can modify the last

compensated block. An I, K vector can only shorten/lengthen the last

compensated block by an amount equal to one active dresser/wheel radius

(see Example 15.5). The direction of the offset is towards the point of

intersection of the I, K vector and the current compensated dresser/wheel

Example 15.5
