Abstract
A numerical controller includes: a program analyzing unit to obtain a first movement end point position of the tool; a direction calculating unit to calculate a synthetic movement direction that maximizes a synthetic velocity, based on an upper limit movement velocity of the tool in each of the two axis directions; an end point position calculating unit to calculate an intersection position of a circle and the synthetic movement direction as a second movement end point position, wherein the circle has as a radius a distance from a rotation center position of the table to the first movement end point position; a rotation angle calculating unit to calculate a rotation angle of the table based on the first movement end point position and the second movement end point position; and a rotation control unit to control rotation of the table based on the rotation angle.
