9700405 Deng A combined experimental and modeling study is being conducted to characterize the frictional behavior of tool-chip interface and to understand the relationship between wear of the cutting tool and the dynamic response of the tool-workpiece system. The experimental observations include recording the dynamic temperature variations near the tool-chip interface, the dynamic, full-field surface deformations on both the chip and the workpiece, and tool wear measurements. These data are used along with finite elements to develop models to predict tool wear. ***

9700405邓正在进行实验和建模相结合的研究，以表征刀具-切屑界面的摩擦行为，并了解刀具磨损与刀具-工件系统的动态响应之间的关系。 实验观察包括记录工具-芯片界面附近的动态温度变化，芯片和工件上的动态全场表面变形，以及工具磨损测量。 这些数据与有限元一起沿着用于开发预测刀具磨损的模型。 ***
