Tool tail radius

Allows us to define a distance (d) to deviate the tool from the curve during the tilting calculation.

The default value corresponds to the tool radius. Whith this value the tool axis can be on the curve.

By putting a value equal to the tool diameter we will then be tangent to the curve.

It is also possible to enter a value bigger than the tool diameter. In this case we have a security distance between the tool and the curve.

 This parameter is available only if the curve is closed.
