This setting defines the machining accuracy tolerance around corners. The initial default value is 0.0250". This means that the control keeps the radii of corners no bigger than 0.0250".
Setting 85 causes the control to adjust feeds around corners in all 3 axes to meet the tolerance value. The lower the value of Setting 85, the slower the control feeds around corners to meet the tolerance. The higher the value of Setting 85, the faster the control feeds around corners, up to the commanded feedrate, but it could round the corner off to a radius up to the tolerance value.
The control can cut corner [1] within tolerance at a higher feedrate than it can cut corner [2].
If Setting 85 has a value of zero, the control acts as if exact stop is active in each motion block.

Assume that the commanded feedrate is too high to achieve corner [1]. If Setting 85 has a value of 0.025, then the control slows the feedrate enough to achieve corner [2] (with a radius of 0.025"). If Setting 85 has a value of 0.05, then the control slows the feedrate enough to achieve corner [3]. The feedrate to achieve corner [3] is faster than the feedrate to achieve corner [2].
