In order to optimize the cutting and feed speed of the NC machining process,a wireless current acquisition sys-tem based on ARM and bluetooth technique was developed to detect the current of the main spindle and feed shaft motor on CNC. The embedded microcomputer based on ARM-M3and Bluetooth module based on CSR BC04 are taken as cores of this sys-tem. The embedded mode for executing multi-channel data acquisition by ARM and HCI UART based bluetooth wireless commu-nication mode are mainly discussed. The experimental result proves that the software and hardware work well,can meet the re-quirements of the current acquisition in the machining procedure,and can measure four-channel AC/DC current signals at the same time. The system possesses a certain anti-interference capability. Its single channel sampling frequency is up to 720 Hz.
