Parallel grinding method has been widely used for advanced optics machining, especially f-θ optics. In order to reduce the dependence on high-precision machine tool with many degrees of freedom (DOF) and obtain high machining accuracy, in this paper, we propose a simultaneous 2-axis method to replace the conventional simultaneous 3-axis method in parallel grinding. Firstly, the algorithm of the simultaneous 2-axis method is explained. Then, the motion control errors and machining errors under simultaneous 3-axis and 2-axis methods are comparably analyzed, respectively. Finally, through grinding experiments, the feasibility of the simultaneous 2-axis method is verified.

Waviness error is one of the most critical errors in the large aspheric lenses grinding and one that has a strong impact on the performance of the optical system. In this article, the waviness error of large axisymmetric aspheric lenses for Xaxis direction as well as Z-axis direction is analyzed by employing grate parallel grinding method. The grinding wheel vibration and Z-axis interpolation pace are regarded as the main causes of the surface waviness error. Furthermore, to reduce the waviness error, the influence of grinding parameters on waviness error is investigated. The waviness errors measured during grinding experiments are in good agreement with the theoretical results and the appropriate grinding parameters are recommended.

“…For dressing technology, the cup grinding wheel dressing technology can get dressing section with high straightness, so it can be able to achieve any convex sections combining this property with dressing motion, and it is easy to get high shape accuracy. [10][11][12][13][14][15] In this paper, the cup grinding wheel dressing technology is used to dress the bonnet tool, and the dressing scheme is set up. In addition, the analysis of dressing process parameters is conducted to give references in actual dressing process.…”

Bonnet polishing is widely used in final processing of optical elements, as the bonnet tool has the characteristic of fine surface adaptability and controllable pressure. For the purpose of ensuring the stability and exact controllability of polishing process, it is necessary to make precise dressing of bonnet tool. In this paper, first a dressing scheme using cup diamond wheel is proposed for bonnet tool, and then the feasibility of the dressing scheme is verified by analyzing the trajectory and the envelope of the diamond particles on the cup wheel. After that, the influences of the dressing process parameters on the dressing efficiency and trajectory distribution are defined through theoretical analysis and MATLAB simulation, and by simulation the dressing process parameters are determined. In addition, a trimmed program with variable speed ratio is proposed to homogenize the dressing tracks. Finally, an experiment was conducted to test the simulation result. This paper provides the theoretical basis for actual dressing process of the bonnet tool.
