基于RTX的参数化插补算法的仿真研究
Simulation Research of Parametric Interpolation Algorithm Based on RTX
摘要
Abstract
In the process of high speed machining of CNC machine tools, because the latter step was always based on the results of previous step during the sampling interpolation technique based on the conventional incremental algorithm, it was easy to cause cumulative error effect.In order to solve this problem, this paper proposed a parametric interpolation algorithm, established the parametric interpolation trajectory model, studied on automatic acceleration and deceleration control principle, independent designed Windows XP SP3 + RTX as software platform for real time extended numerical control system, the simulation experiment was carried out on the platform, the results show that the proposed parametric interpolation algorithm can effectively solve the problem of cumulative error, and reduce the chord error at the same time.关键词
