Cutting motion
The starting point, and therefore the milling direction, is selectable
because the TNC always moves from point

any corner of the surface to be machined.
If you are using an end mill for the machining operation, you can
optimize the surface finish in the following ways:
A shaping cut (spindle axis coordinate of point
spindle-axis coordinate of point 2) for slightly inclined surfaces.
A drawing cut (spindle axis coordinate of point
spindle-axis coordinate of point 2) for steep surfaces.
When milling twisted surfaces, program the main cutting direction
(from point
1
to point 2) parallel to the direction of the steeper
inclination.
If you are using a spherical cutter for the machining operation, you can
optimize the surface finish in the following way:
When milling twisted surfaces, program the main cutting direction
(from point
1
to point 2) perpendicular to the direction of the
steepest inclination.
Please note while programming:
From the current position, the TNC positions the tool in a
linear 3-D movement to the starting point 1. Pre-position
the tool in such a way that no collision between tool and
fixtures can occur.
The TNC moves the tool with radius compensation R0 to
the programmed positions.
If required, use a center-cut end mill (DIN 844).

Questions and answers
Can I change the approach direction when cycle def a stud to avoid obstruction to the right
The provided context does not explicitly mention changing the approach direction to avoid obstruction. However, it describes selecting different axis configurations using the MOD function in the Programming and Editing mode. If modifying the axis configuration allows for adjusting the approach direction, it may be possible. Otherwise, specific cycle parameters should be checked in the programming manual.
