Numerical controller enabling input of relative tool direction to workpiece

摘要

A numerical controller controls a five-axis machining machine that machines a workpiece attached to a table with three linear axes and two rotary axes. The numerical controller inputs a relative tool direction that represents a relative position of the tool direction with respect to the workpiece after the rotary axes are moved by a manual operation, as a vector, roll-pitch-yaw angles, or Euler angles. The numerical controller further converts the relative tool direction thus input into the rotary axis positions of the two rotary axes and drives the two rotary axes based on the rotary axis position thus converted.

1. A numerical controller controlling a five-axis machining machine that machines a workpiece attached to a table with three linear axes and two rotary axes, the numerical controller comprising:
a relative tool direction input unit that inputs by a manual operation a relative tool direction representing a relative position of the tool direction with respect to the workpiece after the rotary axes are moved, as a vector, roll-pitch-yaw angles, or Euler angles; and a rotary-axis position conversion unit that converts the relative tool direction into the rotary axis positions of the two rotary axes, wherein the numerical controller drives the two rotary axes based on the rotary axis positions.
