According to the principle of gear meshing and torus worm drive characteristics to build mathe-matical model, building space coordinate system. Using modeling coordinates measuring principle, The whole test system by high precision linear grating as the feedback element and stepper motor constitute a full closed-loop position control system, Lower computer use ARM STM32F407 as the main controller to com-plete the design of the hardware circuit, upper computer use visual graphic interface LABVIEW virtual in-strument software. Based on the established error detection model and spatial coordinate system, obtained the worm to be tested, the gate location information of the turntable and inductive micrometer head, through error correction processing has been measured torus worm gear tooth surface, the helix error is 8. 7″. The system reduces the controller design and debugging tasks abundantly, and reduces the production cost.
