Research of on-line monitoring of cutting chatter based on embedded system

Considering on the chattering phenomenon which is difficult to real-time, accurate monitoring and control in the process of machine cutting, this paper schemes out a system containing an FPGA based data acquisition of cutting vibration and online control combining FPGA with ARM. In this system, FPGA is used to achieve the main cutting vibration data acquisition, ARM is used for data collection and rapid chatter warning.
