The Optimal Design And Technics Study On The Removing Function Of Polishing Of A Small Tool In Computer Control

Aiming at the polishing of Large Aperture Aspherical Optical Elements, this article systematically analyses the polishing mechanism and concludes the development trend inside and outside. It puts stress on the deep analysis and study of the Polishing process of a Small Tool in Computer Control. According to the Preston equation,it establishes two mathematical models in different modes of movement. Through the simulation based on the emulated material removal function, it gets the polishing process technological parameter. The practical process proves that the result is basically equal to the simulation result, which validates the feasibility of this simulation optimization method and has a certain degree of guiding to practical process. At the same time, this article analyses the edge effect of workpiece process and gets the solutions.Those prepared optical glass elements can reach the following qualifications:K9 aspherical optical glasses are 330mm×330mm,the facial contour precision is up toλ/5;Surface roughness is Rq≤1.5nm.
