Abstract: The present invention provides an on-machine real-time measurement method and system for a full-closed loop five-axis computer numerical control machine tool. In the system, a high-precision coaxial fixture in a displacement measurement component is used for connecting the component with the machine tool spindle; a multifunctional evaluation electronics box reads the signals of the grating scale of each machine axis in real time, and synchronously triggers the displacement sensor to collect the measured workpiece surface information; a synchronous communication module caches the grating scale signals of each machine axis and the measurement signals of the sensor to the FIFO rotation buffering module of the host computer in parallel to reduce the burden of high-speed transmission; and the host computer performs data processing and coordinate transformation of the grating scale data and the measurement information in the FIFO module, and finally obtains the three-dimensional geometric information of the measured workpiece surface.
