摘要
电火花成型加工系统是一种多参数非线性的随机系统,而目前,大多数电火花成型加工机床都是采用定参数加工的方式,机床加工效率低,主要原因在于电加工参数不能随着加工进程的推进而改善,以适应整个加工过程中不同的加工环境。为解决上述问题,提出了一种基于智能控制的加工方法;借助数学工具Matlab设计的模糊控制器对放电间隙的控制和在放电环境恶化下对脉间大小的控制以达到优化放电状态的目的。最后通过实验验证了控制方法的可行性。
The electric discharge machine(EDM) machining system is a multi-parameter non-linear stochastic system,and presently,most of the EDM machines are based on the certain parameters machining.This approach of machining was less effective,the main reason was that the EDM parameters could not be improved at following the process and accommodated the different processing environment in the whole process.In order to solve problems above,a machining method based on intelligent control was proposed.The fuzzy controller designed with mathematical tool of Matlab was used to control the discharge gap and adjust the discharge pulse size in order to achieve the purpose of optimizing the discharge status under very bad discharge environment.A series of experiments are made to identify the feasibility of the control method.
