Industry dynamics
The development of cutting tool materials is closely related to the development of human social life and production. For ancient humans, the understanding and application of "knife" and "fire" is an important symbol of mankind on the stage of history.
The improvement of cutting tool materials promotes the development of human social culture and material civilization. For example, in human history, there have been Paleolithic age, Neolithic age, bronze age and iron age. Corresponding to the stone age is the primitive society of mankind; Corresponding to the bronze age is the slave society of mankind; The iron age corresponds to the feudal society of mankind and its later era.
In traditional machining, tool material, tool structure, mechanical blade and tool geometry are the three requirements that determine the cutting performance of tools, in which tool material plays a key role. After the emergence of computer integrated advanced manufacturing system, the problem of "tool system" should also be considered in the use of tools. In recent years, the emergence and application of various difficult machining materials, the development and application of advanced manufacturing system, high-speed cutting and high-speed cutting, precision machining, "green manufacturing" and "clean manufacturing" have put forward higher and newer requirements for tool materials.
