2D G133, G233, G333/3D G135, G235, G335
The "Coordinate transformation 2D/3D" function is an
The transformation can be programmed as two-dimensional (2D) or three-dimensional (3D).
The programming is done in a fictitious (Cartesian) coordinate system. The machine moves in
a real machine coordinate system.
Special fictitious axes must be defined for the fictitious coordinate system.
If two-dimensional coordinate transformation is selected, plane G18 is active as standard.
If three-dimensional coordinate transformation is selected, plane G17 is active as standard.
Two-dimensional coordinate transformation
Transformation parameter and constant:
a1: offset of the read system in u direction relative to the fictitious zero.
a2: offset of the real system in v direction relative to the fictitious zero.
: angle of rotation of the real system relative to the fictitious system.
