Claim of US Patent No. 9,513,618

1. A numerical controller for controlling a five-axis machine configured to machine a workpiece mounted on a table by means
of at least three linear axes and two rotation axes, the numerical controller comprising:
a tool direction computation unit configured to calculate a tool direction relative to the workpiece as a tool direction vector
representation, a roll-pitch-yaw angle representation, or an Euler angle representation, based on respective positions of
the two rotation axes; and

a tool direction display unit configured to display the tool direction relative to the workpiece on a display, based on the
tool direction vector representation, the roll-pitch-yaw angle representation, or the Euler angle representation which is
calculated by the tool direction computation unit, wherein

if the tool direction vector representation is to be displayed, the tool direction computation unit is configured to calculate
the tool direction relative to the workpiece as the tool direction vector representation, and the tool direction display unit
is configured to display the tool direction vector representation relative to the workpiece,

if the tool direction vector representation is to not be displayed and if the roll-pitch-yaw angle representation is to be
displayed, the tool direction computation unit is configured to calculate the tool direction relative to the workpiece as
the roll-pitch-yaw angle representation and the tool direction display unit is configured to display the roll-pitch-yaw angle
representation relative to the workpiece, and

if the tool direction vector representation is to not be displayed and the roll-pitch-yaw angle representation is to not be
displayed, the tool direction computation unit is configured to calculate the tool direction relative to the workpiece as
the Euler angle representation and the tool direction display unit is configured to display the Euler angle representation
relative to the workpiece.
