Abstract
A numerical controller includes: a program analyzing unit to obtain an end point position of a tool; a first angle calculating unit to calculate an inclination angle of a synthetic feeding direction that maximizes a synthetic torque, based on an upper limit movement torque of the tool in each of the two axis directions; a second angle calculating unit to calculate an inclination angle of a cutting feed direction of the tool based on a start point position and the end point position of the tool; a rotation angle calculating unit to calculate a difference between the inclination angle of the synthetic feeding direction and the inclination angle of the cutting feed direction as a rotation angle of a table; and a servo motor control unit to control rotation of the table based on the rotation angle.
