Productivity and cutting speed is closely related to the increase in cutting speed can increase productivity, while precision and ultra precision machining technology also Machine tool The cutting speed has further increased demand. The concept of high speed cutting is proposed, after long-term exploration, research and development, is widely used in industrial production has only recently started. At present, the processing of steel when the cutting speed has reached 3000m/min, machining cast iron has reached 3000m/min, while cutting speed is achieved when machining aluminum 7000m/min, increased cutting speed than the commonly used many times. In addition to high-speed cutting, the high-speed grinding technology has entered the practical stage. Conventional grinding speed of 30 ~ 40m / s, while the ultra-high speed grinding speed has reached the 150m / s over the. In addition to high-speed cutting and grinding can greatly improve productivity, it also can improve the processing quality, greatly improved the surface quality. High-speed cutting is much higher than the conventional cutting speed under the speed of the cutting process. Conventional cutting speed and tool life relationship is assumed to be linear, that is, the higher the speed of cutting tool, tool wear faster. Half of the 20th century, some researchers have found that in some process, the cutting speed reaches a certain value, the situation started to change, tool wear increased, but the rate continued to rise over this range, they can return to normal processing. After long-term production practice, it was realized for a particular material to be processed for use in cutting speed than the existing area is many times there may be a very ideal cutting conditions. In the cutting conditions, high productivity, long tool life, and cutting force is relatively small. High speed cutting in cutting force is a high-speed cutting technology reduces the physical basis of the development. Why high speed for a certain level, cutting force will be reduced, it was considered as the workpiece material softening due. This softening can be understood as cutting speed faster, cutting shear zone temperature, the material yield limit reduced. There are also researchers that cutting the energy needed to reach a certain speed range, the equilibrium point, with further speed up the cutting speed, cutting force decreased and remained unchanged after a certain speed, then the momentum can change with the cutting slight changes. However, these inferences are not to be from the material deformation mechanism on precise instructions. Therefore, further research should look at cutting the energy needed to produce material deformation with the material deformation is the speed of change, whether the deformation speed (flow rate) exceeds a certain limit of the material deformation after the change, so that the energy required for deformation reduced. Determine the boundaries, seeking the best cutting speed is of great significance. How to define high speed machining? It is generally defined as 5 to 10 times the conventional cutting speed of cutting is called high-speed cutting. I believe that, in the Salomon (Salomon) was established under the premise of theory, the speed limit of specific materials when the cutting speed to the cutting conditions should be referred to as high-speed cutting, high-speed cutting not only divided by speed, but with the physical and mechanical material is closely related to performance and cutting. Although high-speed cutting has become a practical technology, but high-speed cutting mechanism just stop at a pilot stage of exploration and research in basic theory, not yet ripe. Cutting process from the physical and mechanical properties of materials change state, not just by cutting speed to distinguish between conventional machining and high-speed machining is more scientific and reasonable.
