With the continuous development of global industry, the field of mechanical design, manufacturing and its automation is facing in_x005fcreasingly severe energy and environmental pressure. In order to solve the problem of energy consumption and environmental pollution, this paper with energy saving design ideas as the core, in the material selection as the research object, by optimizing the material selection, using advanced numerical control technology and green processing technology, put forward a series of solutions, aims to provide reference for mechanical design and manufacturing and automation practitioners, promote the industry towards more sustainable and energy saving direction.

Under the perspective of the rapid development of information technology, the field of mechanical design and manufacturing has ushered in unprecedented changes. Traditional design methods and manufacturing processes gradually show limitations under the wave of digitalization and intelligence, such as low work efficiency, limited design accuracy, high production cost and other problems have become the bottleneck of the development of the industry. In order to solve these problems, this paper focuses on the integrated application of computer aided design (CAD), automatic manufacturing technology and intelligent monitoring system, aiming to improve the design accuracy, optimize the manufacturing process, reduce costs, so as to promote the development of mechanical design and manufacturing industry to a more efficient and accurate direction.

With the continuous development of science and technology, mechanical design and manufacturing and its automation have become an important part of modern industry. It plays a key role in improving production efficiency, optimizing production mode and reducing production cost. However, with the continuous development of social economy and the continuous innovation of technology, the machinery manufacturing industry is also facing higher requirements and more severe challenges. Therefore, this paper will deeply discuss the development direction of mechanical design and manufacturing and its automation, in order to provide useful reference andreference for the future development of related industries.
