如何控制好放电间隙状态是提高电火花机床性能的关键之一。而识别放电间隙状态与建立描述其特性的数学模型是设计控制系统和改进性能的前提。一、放电间隙状态的分析放电过程中,因受各种因素变化的影响,如间隙的大小,脉冲参数,工件的几何形状,加工深度,工作液的压力、流场分布,废屑在间隙内分布情况以及其它大量随机因素,使间隙状态在迅速地变化着。
How to control the state of discharge gap is one of the keys to improve the performance of EDM. Recognizing the state of the discharge gap and establishing a mathematical model that describes its characteristics is a prerequisite for designing a control system and improving performance. First, the discharge gap state analysis Discharge process, due to changes in various factors, such as the size of the gap, pulse parameters, the workpiece geometry, processing depth, pressure of the working fluid, flow field distribution, debris in the gap Distribution and a large number of other random factors, the gap state is rapidly changing.
