Preferred 5X Lead Angle

Define a 5X lead angle which improves the machined surface quality (see Parallel 5X Lead). This is the angle between the Z axis of the active UCS and the tool axis.

This parameter is displayed if the Parallel 5X Lead Machining Method option is selected.

The lead angle is implemented as follows:

• Machining is at a preferred constant lead angle whenever possible.
  

• At a point that the constant lead angle may cause a gouge, the tool gradually straightens.
  

• When the tool has passed the obstacle, it gradually returns to the original lead angle.
