This equipment grant supports research directed at developing qualitative and quantitative global correlations between process performance, material properties, and machining parameters; an off-line optimization scheme; and an on-line monitoring and computer-based control system for wire electro- discharge machining (WEDM). The on-line monitoring device and adaptive control system is based on stochastic models and the spectrum analysis of the gap voltage, current, and power signals. The stochastic models of the gap condition provide necessary information about random distribution of thermal load required for developing a realistic thermal model and a better understanding of the microscopic behavior at the gap.

这笔设备赠款支持旨在开发工艺性能、材料特性和加工参数之间定性和定量全球相关性的研究；离线优化方案；以及电火花线切割加工(WEDM)的在线监测和基于计算机的控制系统。在线监测装置和自适应控制系统基于随机模型和对间隙电压、电流和功率信号的频谱分析。缝隙条件的随机模型提供了有关热负荷随机分布的必要信息，这是开发真实的热模型和更好地理解缝隙处的微观行为所必需的。
