Coordinate Control
Chapter 11
11-32
CENTER
Use this parameter to assign the center of rotation. The center of rotation
is a point on the machine coordinate system about which all the work
coordinate systems are rotated. Enter a coordinate value for each axis in
the selected plane. The default value for the center of rotation is (0, 0).
VECTOR
This parameter is optional, and is superseded by any entered value for the
ANGLE parameter. If used, the values entered here define the coordinates
of the “head” of a vector. The “tail” of this vector is the center of rotation
(described above). The resulting angle between this vector line and the
first plane axis (described above) is the angle that the work coordinate
systems are to be rotated. Again, all work coordinate systems are rotated
about the point defined by the CENTER parameter. The default values for
VECTOR are (0, 0). If values are entered for Vector, the angle of rotation
that is generated is displayed for the Angle parameter.
ANGLE
Use this parameter to assign the angle that the work coordinate systems
rotates about the above defined CENTER point. If you enter a value here,
the control cancels any value entered for the VECTOR parameter. The
ANGLE parameter has units of degrees, with a default of zero. Positive
angles result in rotation clockwise from the primary axis for that plane (as
defined in plane above). If no value is entered, the control displays the
current angle as defined by the Vector parameter here.
