Development status of machining.

With the rapid development of modern Machining and rapid development of mechanical machining technology, slowly emerged in a number of advanced mechanical machining techniques, such as micro mechanical machining technology, rapid prototyping technology, precision and ultra precision machining technology etc..

1. Micro mechanical machining technology

With the development of Micro / Nano, Science and Technology, micro machines characterized by small shape, small size and minimal operating scale have become a high and new technology for people to recognize and transform the micro world. Micro mechanical have wide potential applications in aerospace, precision instruments, biological medicine and other fields because of their ability to operate in confined spaces without disturbing the working environment and objects, and become an important means of nanotechnology research, which has been highly valued and listed as the key technology in 21st Century.

2. Rapid Prototyping Machining Technology

Rapid prototyping technology is developed in the 20th century, according to the CAD model to quickly create a sample or parts. It is a method of material addition and machining, that is, through the orderly accumulation of materials and three-dimensional forming. Rapid prototyping technology integrates CNC, material technology, laser technology and CAD technology and other modern scientific and technological achievements. It is an important component of modern advanced machining technology.

3. Precision and ultra precision machining technology

Precision and ultra precision machining is an important component of modern machining technology. It is one of the important indexes to measure the level of a high-tech manufacturing industry in a country. Since 1960s, with the development of computer and information technology, put forward higher requirements on the manufacturing technology, not only require high dimension and shape accuracy, and require high surface quality. It is in this market demand, ultra precision machining technology has been rapid development, a variety of processes, new methods continue to emerge.
