The symbol of human beings becoming "modern people" is the manufacturing tool. The various stone axes, stone hammers and simple rough tools of wood and leather in the Stone Age were the pioneers of the machinery that emerged later. The evolution from manufacturing simple tools to manufacturing modern machines consisting of multiple parts and components has gone through a long process. Thousands of years ago, mankind has created hoes and mills for shelling and smashing of grains, citrus and hoes for lifting water, vehicles with wheels, ships and paddles, rafts, rudders, etc. that sail on rivers. The power used develops from the physical strength of the person to the use of animal power, water power and wind power. The materials used have evolved from natural stone, wood, earth and leather to man-made materials. The earliest man-made materials were ceramics, and ceramic cars made of ceramic wares were already complete machines with three parts: power, transmission and work. From the Stone Age to the Bronze Age, and then to the Iron Age, the development of the blower used to blow the fire has played an important role. There is a strong enough air blower to get a high enough furnace temperature for the metallurgical furnace to refine the metal from the ore. In China, from 1000 to 900 BC, there were already blowers for smelting and casting, and gradually developed from man-made blast to animal power and water blast. Before the 15th to 16th centuries, mechanical engineering developed slowly. However, in the practice of the millennium, considerable experience and technical knowledge have been accumulated in the development of machinery, which has become an important potential for the development of mechanical engineering. After the 17th century, capitalism appeared in Britain, France, and Western European countries, and commodity production began to become a central issue in society. In the late 18th century, the application of steam engines was extended from the mining industry to textiles, flour, metallurgy and other industries. The main materials of the manufacturing machinery are gradually changed from wood to tougher, but difficult to use hand-processed metal. The machinery manufacturing industry began to form and became an important industry for decades. Through the ever-expanding practice, mechanical engineering has evolved from a distracting skill that relies mainly on the individual talents and crafts of craftsmen to a theoretically guided, systematic and independent engineering technique. Mechanical engineering is the main technical factor that contributed to the industrial revolution of the 18th to 19th centuries and the large-scale production of capitalist machinery. Motivation is an important factor in the development of production. In the late 17th century, with the improvement and development of various machinery, as the demand for coal and metal ore increased year by year, people felt that relying on manpower and animal power could not raise production to a new stage. In the UK, textiles, milling and other industries are increasingly setting up workshops by the river, using water wheels to drive work machines. However, the groundwater in mines such as coal mines, tin mines, and copper mines could only be upgraded and eliminated with a large amount of animal power. Under such production needs, Newcomer's atmospheric steam engine appeared in the early 18th century to drive the mine drainage pump. However, this steam engine has a high fuel consumption rate and is basically applied only to coal mines. In 1765, Watt invented a steam engine with separate condensers, reducing fuel consumption. In 1781, Watt created a steam engine that provided rotary power, which expanded the application range of the steam engine. The invention and development of steam engines have made mechanical and industrial production, railways and shipping mechanically powered. The steam engine is almost the only power source in the 19th century, but the steam engine and its boilers, condensers, and cooling water systems are bulky and cumbersome, and the application is inconvenient.
