Based On GMM On The Ball Screw Axis To Error Compensation On The Application Of Research

The CNC machine tools treating accuracy is that affecting the treating accuracy workpiece dimension accuracy a direct cause, the workpiece ultimateness are processed is that displacement error decides from relativity between the machine tool cutter and workpiece. That error now is compensated is to set off from the software angle mainly, this can not comply with the error problem solving a problem essentially. Our country tool machine accuracy's being subjected to a check and supervision is also machine tool accuracy to fall behind, so compensates to study its error margin from the hardware is have much of necessary. With Tb-Dy-Fe as a representative of the rare-earth giant magnetostrictive material functional materials, that it has magnetism so that expansion and shrinkage responding to speed greatly, quickly, the magnetism- mechanical coupling modulus is big, the hysteresis waits for merit for a short time, is that ideal micro displacement drives material. Combined with giant magnetostrictive material characteristics, according to the performance indicators, given the task of magnetic circuit in the displacement of the mechanical structure and the compensation system of magnetic structure, positioning control system for the preliminary design and simulation.This article in the following aspects:1,Giant magnetostrictive material working characteristics are analyzed, and for the ball screw axial compensator design preparation;2,And on the ball screw on the rod of axial error theory, ball screw axial stiffness error analysis, i.e., to realize its compensation, must determine the ball screw axis errors, using the elastic mechanics determine the ball screw axis errors. To determine the ball screw axial compensator range;3,Ball screw axis of the compensator is designed. In the design process determine the overall structure of the compensator, on the basis of giant magnetostrictive choice GMM model, electromagnetic structure design and temperature control device design and final design results. For compensator system modeling and analysis software ANSYS, the basic parameters of the electromagnetic;4,Ball screw axis of static and dynamic compensator mathematical modeling and MATLAB simulation and simulink.this simulation result analysis;5,ANSYS software is used to design the axial compensator using the static electromagnetic field finite element analysis is carried out.
