14.27.1 Outline

By selecting the hypothetical coordinate system to be machined, axis can be moved with manual feed (JOG, HANDLE or
INCREMENTAL) in the coordinate system with the 3-dimensional manual feed function.
When a travel command is executed in the hypothetical coordinate system, the NC can move more than one axis according to
the tool orientation and table inclination, which facilitates the setup process.
This function has two feed modes: "Feed in hypothetical coordinate system" and "Rotation with the tool tip as the center".
A travel command to linear axis is processed as a feed in hypothetical coordinate system, so the manual feed is carried out in
hypothetical coordinate system.
A travel command to rotary axis is processed as a rotation with the tool tip as the center. The commanded rotary axes and the
three linear axes are used to perform the manual feed while maintaining the positional relationship between the workpiece
and tool tip.
