Technology Transformation

This paper focuses on the analysis of the aviation industry machining technology transformation, and its current development status. The entire development plan for numerical control machine tool needs to be perfected, and the balance of numerical control technology development has to be strengthened. Additionally, the utilization rate of numerical control machines is relatively low; thus, raise the rate of equipment, numerical control, and numerical control equipment usage, and enhance the mechanical processing technology management task. Its aim is to improve aviation industry machining efficiency, which leads to a good development in China’s aviation industry.

Investigation And Study

In recent years, investment on China’s exhibition buildings rises sharply, but problems like over-warming of the exhibition hall construction, structural surplus, and low utilization rate occur. On the basis of analyzing the current development status of China’s exhibition buildings, this paper takes Nanning International Convention & Exhibition Center as an example to develop the investigation and study, and proposes the sustainable development strategy pointedly from building space environment and planning management, etc. The study is expected to provide reference for the sustainable development of similar domestic exhibition buildings.

Extrusion Forming

In this article, it mainly describes the use of extrusion production process as an example of the special shaft. It gives us a full analysis from the structure of the product, the material problems, the key technical problems needed to be solved, blank preparation processing and the process of extrusion forming. It also introduces the blank dimensions and the calculation method of the extrusion pressure. The method of blank lubrication processing and the process of designing extrusion mould.We are not unfamiliar with the center shaft of the bike. It is one of the important parts in bicycle bottom bracket. It is also a key part to determine the quality of the bicycle. Generally speaking, materials are used is 20 steel. The roughness of the surface is moderate. But the requirement of the product precision is high. We can get it by using mechanical processing method. But it is processing and the efficiency is low. While the utilization rate of mental material is low. So the production costs high. Because the parts production patch is large and the annual production is hundreds of thousands of pieces. In my opinion, it is more reasonable for us to adopt the technology of producing the parts with the cold extrusion precision molding process. Then we can save the materials, improve the efficiency of producing parts, lower the production parts and then meet the requirement of mass production.

Since computer numerical control machine tool is composed of multiple meta-action units to achieve one specific function, including the meta-action units' own quality, it still needs to control the coupling relationships among different meta-action units' quality characteristics to guarantee the whole machine's quality. In this article, a method of quality characteristic decoupling planning based on meta-action unit for computer numerical control machine tool was proposed. Firstly, the coupling constraint models based on meta-action unit were established. Secondly, the comprehensive coupling strengths of meta-action units were calculated and introduced into the design structure matrices. Thirdly, multidisciplinary design optimization method was adopted to obtain the optimized control sequence of different meta-action units' quality characteristics. What is more, automatic pallet changer rotary motion of computer numerical control machine tool was taken as an example to illustrate the rightness and effectiveness of this method.
