Patent number: 12186847Abstract: Disclosed is a selective field-assisted machining system. The system includes a micron-level high-speed identification module, an in-situ laser assisted module, an ultrasonic vibration module, an energy field loading high-speed control module, and a diamond tool. The micron-level high-speed identification module is used to quickly identify the type of a material substrate of a workpiece to be processed, process the identification information into a corresponding control signal, and send same to the energy field loading high-speed control module to implement selective processing of the workpiece to be processed, i.e. to process brittle particles using in-situ laser assisted machining and to process a soft metal substrate using ultrasonic vibration processing. In the present invention, ultra-precision cutting of brittle particles and a soft metal substrate can be completed at the same time in a single processing process.Type: GrantFiled: December 25, 2023Date of Patent: January 7, 2025Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Jianfeng Xu, Zhengding Zheng, Jianguo Zhang, Kai Huang, Mao Wang, Xiao Chen, Junfeng Xiao
