The paper introduces a PXI system for detecting the temperature and displacement of CNC machine tool. The hardware of the system composes of highperformance embedded controller NI PXIe-8840, 9-slot chassis NI PXIe-1078 in which each slot accepts PXI Express module and X Series Data Acquisition Module NI PXIe-6341. Lab VIEW (Laboratory Virtual Instrument Engineering Workbench) software is used to process the acquired data from the digital potentiometer temperature sensor and grating displacement sensor according to CNC performance requirements. The developed system can be used to measure temperature, displacement, speed and acceleration accurately.
