NUMERICAL CONTROLLER

PROBLEM TO BE SOLVED: To provide such a numerical controller that a moving axis has no effect on acceleration and deceleration control, in the moving axis having no effect of the variation in the moving direction between continued moving blocks on working accuracy. SOLUTION: A positioning instructions section 2 inputs the continued moving blocks of simultaneous linear interpolation instructions with respect to a plurality of moving axes from an NC (Numerical Control) instructions section 1, forms the vector component of the moving axes except a standard axis to zero to calculate an angle formed by the continued moving blocks when the standard axis as an axis specified out of the plurality of moving axes in the continued moving blocks is present, and performs the acceleration and deceleration control between the continued moving blocks on the basis of the angle. Thus, the operation of the moving axes having no effect on the working accuracy becomes free from having effect on the acceleration and deceleration control between the moving blocks by specifying the moving axis having effect on the working accuracy as the standard axis.
