Problems solved by technology

But utilize the above-mentioned equipment to process and have following technical defect: (1) because only by the position servo control of CNC machine tool cutting process, the part is processed in the processing process, and can't carry out real-time control to the lapping and polishing force acting on the part, thereby make The polishing force of the curved surface polishing process is uncertain and inconsistent, resulting in uncertain and inconsistent finishing quality of the part surface; (2) The cost of equipment is high. Generally, the value of each CNC machine tool is in the millions or even tens of millions, which is extremely high. Great hindrance to the popularization of production of aspheric parts processing

Abstract

The invention discloses a polishing method of non-spherical surface optical parts, which has the advantages that the polishing normal force can be directly controlled in the processing process by the polishing method, the problem of inaccurate force control caused by softening mechanical system force/position coupling problems can be solved, and the invention is favorable for obtaining stable and uniform curve surface outlines, and improves the part surface finishing processing quality. In addition, a softening control mode is adopted for processing the non-spherical surface optical parts, high requirements on the mechanical system precision of the precision finishing is avoided, the manufacture cost of equipment is reduced, and the invention is favorable for popularized application. In addition, the method of the invention has simple processing principle, and is favorable for hardware design and software development.

Description

technical field [0001] The invention relates to a method for processing parts in the mechanical field, in particular to a method for grinding and polishing aspheric optical parts. Background technique [0002] Aspherical optical parts have attracted extensive attention of researchers because of their good optical properties. In recent years, the research and development of aspheric optical parts polishing technology and equipment generally use ultra-precision multi-axis CNC machine tools as a platform, and process in the form of multi-axis CNC interpolation motion servo to realize the numerical control of the aspheric surface polishing process. Precision, to a certain extent, improves the processing efficiency of lapping and polishing. But utilize the above-mentioned equipment to process and have following technical defect: (1) because only through the position servo control of CNC machine tool cutting process, parts are processed in the processing process, and can't carry ...
