Abstract

The invention discloses a numerical control machining method of an airplane model. The method specifically comprises the following steps that firstly, the airplane model is partitioned according to structural characteristics; secondly, back faces of the airplane model are independently machined according to partitions in the first step, and process bosses are machined on the back faces of the airplane model; thirdly, the front faces of the airplane model are independently machined according to the partitions in the first step; and fourthly, the process bosses on the back faces of the airplane model are cut away, or the machined process bosses on the back faces of the airplane model are machined into airspeed heads, surface treatment is carried out by waxing polishing paste or applying a grinding agent, and the machining of the airplane model is finished. According to a method for vibration restraining of numerical control machining of an airplane, the problem that complex airplane curved surfaces and airplane thin-wall pieces vibrate during numerical control machining is solved, the consistency of the profile machining quality and the exterior surface size is guaranteed, and meanwhile production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of model processing methods, and relates to a numerical control processing method of an aircraft model. Background technique [0002] The development of simulation models has a long history. In the records of ancient Chinese history books, there are many descriptions about simulation models. In modern archaeological excavations in my country, some ceramic and wooden simulated military models have also been unearthed, such as the earliest ship model in China—a military model of a ceramic canoe found in the Neolithic site of Hemudu in Yuyao, Zhejiang, and Terracotta Warriors and Horses of Qin Shihuang unearthed in Xi'an. The most attractive part of the model collection is not only to test the hands-on ability, but also to see whether there is sufficient background knowledge and understanding of military history. After an airplane model is released and sold, with the progress of time and the continuous improve...
