Research on Cutting Parameters Database Based on Spacecraft Product Characteristics

Abstract

Cutting parameters affect the production and processing efficiency and the quality of products. The characteristics of single-piece and small-batch production of spacecraft products result in a large number of cutting parameters. Due to the lack of centralized management methods, cutting parameters in the production site are not unified, which seriously affects the processing efficiency and quality of products. In response to a large number of cutting parameters and the lack of centralized management, the production resource library is completed by establishing a spacecraft product feature pedigree. Taking the product characteristics as the carrier, the production resources as the optional factors, and the forces in the cutting process as the evaluation criteria, the whole life management mechanism of cutting parameters is established to unify the cutting parameters in the production process and complete the establishment of the cutting parameter database. The interface between the programming platform and the cutting parameters library is developed for a low reuse rate of cutting parameters. With typical features as the carrier, the cutting parameters are packaged and transmitted to the programming platform to provide reliable cutting parameters for feature automatic programming, which improves the reuse rate of cutting parameters and simplifies the numerical control programming operation. The results show that the reuse times of cutting parameters are more than 8000 times, effectively ensuring the machining efficiency and quality consistency of products.
