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
; Orientation transformation on.
; Interpolate tool orientation as a vector.
; Tool orientation in the plane.
; Select large-radius circular interpolation.
; Orientation in the Y/Z plane is rotated
through 45 degrees, orientation (0,1, 2,1/
√2, 1/√2) is reached at the end of the
block.
; Orientation programming on the outside of
the taper:
; The orientation vector is interpolated on
the outside of a taper with the direction
(0,0,1) up to the orientation (1/√2,0,1/√2)
in the clockwise sense, the angle of
rotation is 270 degrees.
; The tool orientation goes through a full
revolution on the outside of the same taper.
