Precision Control of Micromechanical Automatic Manufacturing Based on Nanotechnology

Segment precision affects the accuracy level of micro machine manufacturing, only for the linear change is not big, more straight segment control, easy to cause dimensional deviation, so a precision control method of micro machine automatic manufacturing based on nanotechnology is proposed. The white noise is selected as random sequence to eliminate the concentrated trend and high frequency components in the input and output data. The precision control parameters of micromechanical automatic manufacturing are adjusted by setting the current loop, speed loop and position loop. According to the setting results, the contact area of micromechanical automation manufacturing is established in the coordinate system o-xy, and the equivalent curvature radius of the contact surface is calculated. Through coordinate transformation, the pressure distribution in the circular contact area is obtained, and the precision control area model of micromanical automation manufacturing is established. According to the model and the finite element analysis method, the control flow is designed to realize the precision control of the automatic manufacturing of micromachines. The experimental results show that the design method can reduce the precision control error of the automatic manufacturing of micromachines and improve the construction level of micromachines.
