Abstract
A numerical control apparatus includes: a program input unit that reads a tool distal end position and a tool posture and generates designated position sequences of the linear axis and designated position sequences of the rotation axis; a distal-end-position-curve generating unit that generates a tool distal end position curve concerning the tool distal end position; a tool-posture-curve generating unit that generates a tool posture curve concerning the tool posture associated with movements of the tool distal end position; an interpolation calculating unit that calculates an interpolation point of the tool distal end position, calculates an interpolation point of the tool posture, and calculates an interpolation point of a machine position of the linear axis; and an interpolation output unit that moves the linear axis to the calculated interpolation point of the machine position and moves the rotation axis to the calculated interpolation point of the tool posture.
