The system includes ADLINK motion control card PCI8134, LEETRO stepper motor drivers DMD 402A, and tables with LEETRO DM4240A stepper motors. The system uses ADLINK PCI8134 to send stepping pulse signal PUL and direction level signal DIR to control the stepper motor’s rotation angle and direction, achieving the motor’ positive and negative rotation, acceleration, constant speed and deceleration, then achieving the radial motion of table’s Zaxis slider along the surface of the measured part, the axial motion of Xaxis slider along the surface of the measured part and the spindle rotation for the measurement of roundness and cylindricity. 169。 Experimental conclusions In this paper, the stepper motor’s control system is functional unit of the roundness and cylindricity measuring virtual instrument. By calculating the relationship between the sensor’s acquisition rate and the stepper motor’s speed, achieving the stepper motor’s openloop control, finally getting the collection of the reliable data and reliable operation of subsystems,
