Manufacturing technology in order to meet increasingly diverse face of the product, higher productivity and environmental requirements, have appeared in high-speed cutting, dry cutting and other new processing technologies. High-speed cutting technology allows the cutting processing time was significantly reduced and this is to use the new tool materials and coatings achieved results. Based on this, by cutting parameters to further improve the potential for increased productivity has been very limited.
Another way to improve productivity is to minimize overhead time. First, the decomposition of complex parts for many processes and uses many tools processing method of accounting for a lot of processes before and after the tool change time and transmission time. To improve productivity and reduce time to have practical significance. One has been proven a very effective approach is to use the combination of multi-function tool features a single standard to replace the tool, and proper tool selection and rational use of combination will get the desired effect.

Currently more and more complex combinations of tool structure recognized by the user. Combination of tools to promote the development and expansion of scope of use, tool manufacturers in the development of these tools, we must take into account users may encounter problems, find solutions, to take various measures, including the development of certain flexible and controllable tool the development of new coating technologies, tool material and geometry, in order to reduce tool costs, even the tools to manufacturing production bases to produce low-cost regions.

Flexible tool but only in combination or without transformation machine connections and control system can only be successful promotion; the new combination tool and process efficiency will each related factors, such as substrate material, coating material, geometry, etc. factors, should be for specific optimization of processing objects, form a comprehensive advantage. At the same time, due to time savings while supporting increased level of utilization of these advantages, to obtain the effect of increased productivity. This to improve the cutting efficiency and reduce the auxiliary time trend of integrated application will promote the wider use of composite tools.
