PURPOSE:To obtain the vertical vector of a model shape in the case of a numerical information-orientation system of copying action, by constituting the system such that a vector component of the displacement perpendicular to a copying face is used as it is. CONSTITUTION:A copying action controller 5 comprises a control unit 51, speed control part 52, A/D converter part 53, numerical information-orientation control part 54 and a numerical information memory part 55. A displacement signal from a stylus 3 is input to the control part 51, and a speed instruction (f) is fed to the control part 52 on the basis of this displacement. The control part 52 drives electric motors, Mx, My, Mz of respective three-axes, and the stylus 3 is moved in such a manner as to profile a model shape. While a displacement from the control unit 51 is digitalized in the converter part 53 and fed to the control part 54. Numerical information of a moving position is generated in the control part 54 on the basis of a signal from position detectors Dx, Dy, Dz. In such way, a vector of the model shape in the vertical direction is obtained. |
