11.12 THREE-DIMENSIONAL COORDINATE CONVERSION
General
Coordinate conversion about an axis can be carried out if the center of
rotation, direction of the axis of rotation, and angular displacement are
specified. This function is very useful in three-dimensional machining
by a die-sinking machine or similar machine. For example, if a
program specifying machining on the XY plane is converted by the
three-dimensional coordinate conversion function, the identical
machining can be executed on a desired plane in three-dimensional
space.

Three-dimensional coordinate conversion
In three-dimensional coordinate conversion mode (G68), the following
two types of manual operation (jog feed, manual incremental feed, and
manual handle feed) are supported:
(1) Operation in a workpiece coordinate system (with three-
dimensional coordinate conversion not applied)
(2) Operation in a program coordinate system (with three-
dimensional coordinate conversion applied)
For information about which type is used, refer to the manual provided
by the machine tool builder.
