PURPOSE:To avoid such a case where the working efficiency is deteriorated owing to increase of the teaching points by inputting a basis vector which shown each interpolation point in plural vectors and calculating the interpolation points needed for drawing the moving locus of a tool produced by repetition of the interpolating actions. CONSTITUTION:A vector input means is provided for input of a basic vector which shown each interpolation point in plural vectors in terms of a prescribed interpolating action carrier out based on an interpolation point. In addition, an interpolation point calculating means is used to calculate the interpolation points needs for drawing the moving locus of a tool produced by repetition of the interpolating actions. That is, said basic vector is inputted from the vector input means and the interpolation point calculating means calculates the interpolation points needed for drawing the moving locus of said tool. Thus it is possible to obtain the moving locus of a tool without teaching many interpolation points.
