Requirement:
The tool must be perpendicular to the working plane and the positive direction of the infeed axis
points in the direction of the tool base.
Specifying CUT2DF activates the tool radius compensation in the rotated plane.
2.12.6 Programmable frame rotations with solid angles (ROTS, AROTS, CROTS)
Rotations of the workpiece coordinate system can be specified in solid angles with the ROTS,
AROTS and CROTS statements. Solid angles are the angles formed by the intersections of the
plane rotated in space with the main planes of the not yet rotated WCS.
Note
Geometry axis identifiers
The following definition is made as an example for the further description:
● 1st geometry axis: X
● 2nd geometry axis: Y
● 3rd geometry axis: Z
As shown in the following figure, the programming of ROTS Xα Yβ results in an alignment of
the G17 plane of the WCS parallel to the displayed inclined plane. The position of the zero point
of the WCS remains unchanged.
The orientation of the rotated WCS is defined so that the first rotated axis lies in the plane
formed by this and the 3rd axis of the original coordinate system. In the example: X' is in the
original X/Z plane.
