摘要：Aiming at the problem of low efficiency and low accuracy of traditional interpolation algorithms, a new numerical control interpolation method-velocity interpolation, is presented in this paper. The realization steps of the quadratic curve in the numerical control system are described. Through the analysis of the error caused by the error caused by the stepper motor in the stepper motor control system, a correction method is proposed to improve the machining accuracy. The simulation program is developed by VC++ to simulate the process of the quadratic curve, which is the representative of a parabola, and the feasibility of the modified method is verified.
