Interpolation technology as a key technology of CNC machining, can be widely used interpolation methods, the degree of error and putational efficiency of the algorithm, both the plexity of the decision, the CNC machining accuracy and efficiency of equipment parts. Currently, for some interpolation technology researches have been very mature, therefore, on this basis, this paper studies CUBIC spline interpolation technology in CNC machining systems, to achieve two major areas: (1) Analysis of theoretical posture CUBIC spline interpolation technology, and reasonable CUBIC spline interpolation technique applied to CNC machining systems 。 (2)With C as a platform to develop a verification system to verify the effect of CUBIC spline simulation. 【 Keywords】 CUBIC spline interpolation, numerical control systems, C 沈陽(yáng)師范大學(xué)本科畢業(yè)論文 ― III― 目 錄 1
