Optimization of CNC Optical Curve Grinding of Mold Parts Using Orthogonal Design

As an important process equipment in industrial production, mold is one of the important foundations for the development of various sectors of the national economy. It plays an extremely important role in modern industrial production. Mold manufacturing integrates many disciplines such as machinery, electronics, chemistry, optics, materials, computers, and information networks, etc., to develop larger, more precise, more complex, and more economical. The technical content of mold products continues to increase, and mold manufacturing cycles continue to shorten. With the development of machinery, electronics, computers, new materials and other technologies, a large number of precision processing equipment has been applied in the high-precision mold industry. These precision processing methods have made the precision of precision molds continuously improved. In the late 1980s, the precision of precision molds can reach 5 zi m. The main use of precision slow wire cutting machine tools. The precision of the mold has reached 1 zi m. High-precision CNC optical curve grinders are commonly used in the processing of key mold parts. application. In the use of optical curved grinding, due to the many factors that affect the quality of the processed workpieces, and the more complex interactions, the processing technology of optical curved grinding can only be a long-term experience accumulation. It is difficult to obtain an optimized and reasonable processing process without scientific theoretical guidance. Orthogonal experimental design is referred to as orthogonal design. It is a method of scientifically arranging and analyzing multi-factor experiments using orthogonal tables. It effectively reduces the number of experiments. It can effectively solve the optimization of process parameters that affect the quality of the workpiece by the multi-factors of light curved grinding. The problem provides theoretical guidance for the process optimization of CNC light curved grinding.

Experimental method The Japanese GLS5PCNC optical curve grinder is currently a very precise processing machine tool. Its processing accuracy can be 001mm surface finish can reach Ra003 Zim. This processing technology experimental research is carried out on this type of machine tool. The precision and smoothness of the processed parts are the main indicators for checking the processing of the machine tool when processing the parts on the optical curve grinder. Because the final accuracy of the processed parts needs to be roughed and finely ground to complete. It is difficult to describe the effect of the process parameters and the finish parameters are the reaction An index of processing accuracy is more intuitive to measure, so the smoothness parameter is used as an index that affects the accuracy of the workpiece to study the influence of process parameters.
