If the blank and finished-part contours do not coincide, ManualTurn
will define the connection between the blank and the finished part.
If the angle between the straight lines and the Z axis is greater than
zero, the connection is upward, if the angle is less than or equal to
zero, the connection is to the side.

Process machine relief cuts (yes/no)
A free contour can contain relief cut elements which is not the case for
stock removal cycles in STOCK REMOVAL mode. You can specify
whether the relief cut elements are to be machined or not.
Machine tool angle (yes/no)
The tool angle can be included in machining, for example, to avoid
contour violations on relief cut elements.
If the tool angle is not taken into account, ManualTurn will assume that
a mushroom is used for stock removal.
