The machinery industry is an important pillar of China’s economic construction. The design stage of traditional mechanical manufacturing is very difficult. This leads to the backwardness of mechanical equipment in our country. With the development of computer technology, great changes have taken place in the machinery industry[6]. According to the means of foreign machinery manufacturing, scholars believe that computer technology can promote the progress of machinery manufacturing level. Computer technology is also widely used in mechanical manufacturing. This paper describes the shortcomings of the current mechanical manufacturing technology. This paper also describes some applications of computer mechanical manufacturing technology.

In 1991, Väisälä discussed the extension property of quasisymmetric mappings in Banach spaces. In 2009, Haïssinsky got an extension property of quasisymmetric mappings in metric spaces. The purpose of this paper is to establish an extension property of quasimöbius mappings in metric spaces.

In this paper, we investigate the relationship between the weak min-max property and the diameter uniformity of domains in Banach spaces with dimension at least 2. As an application, we show that diameter uniform domains are invariant under relatively quasimöbius mappings.
