Supplementary conditions
Transformations
Transformations are not permissible in curve tables. TRAANG is an exception.
TRAANG
If TRAANG is programmed, the rule of motion programmed in the basic co-ordinate system is
transformed to the associated machine co-ordinate system. In this way it is possible to program
a curve table as Cartesian co-ordinates for a machine with inclined linear axes.
The condition that stipulates that "the direction of motion of the leading axis must not reverse
at any point of the rule of motion" must then be met in the machine co-ordinate system. Please
note that this condition in the basic co-ordinate system does not have the same meaning as
in the machine co-ordinate system, since the contour tangents are changed by the
transformation.
