Lead in and Lead out Characteristics

First define the value of the radius for the lead in and the lead out. The two values can be different.

If this value is 0, there is no radius done and the other parameters are not available.

In this example, the diameter of machining is 10 mm, the lead in and lead out radii are 7.5 mm.

.

An angle of aperture for the radius can also be defined.

This angle define the length of the radius, in the following example the lead in radius is 90°, it is a quarter of circle.

The lead out angle is only 45 °.

Finally define if the radius is constant or evolutive regarding Z axis.

In the example, the lead in radius is evolutive whereas the lead out radius is constant.
