7.2 Three, four and five axis transformation (TRAORI)
Interpolation on the outside of a taper
with
direction vector in the
clockwise/counterclockwise direction of
the taper and end orientation or
tangential transition and
specification of end orientation
or
specification of end orientation and
intermediate orientation on the outside of
the taper with
polynomials for angle of rotation and
polynomials for opening angle
Interpolation in the plane (large-radius circular
interpolation)
Interpolation on the peripheral surface of a taper in
the clockwise direction
Interpolation on the peripheral surface of a taper in
the counterclockwise direction
Interpolation on the peripheral surface of a taper with
tangential transition
Programming of a rotary axis of the taper (normalized
vector)
Opening angle of taper in degrees
Traverse angle smaller than or equal to 180 degrees
Traverse angle greater than or equal to 180 degrees
Interpolation on the peripheral surface of a taper
Intermediate orientation (programming as normalized
vector)
Angle of rotation of the orientation about the direction
axis of the taper
Opening angle of the taper
Apart from the different angles, polynomials can also be
programmed up to the 5th degree
