Different green design and traditional design method of cutting tool. Green design including concept design, technical design, manufacturing and processing, use and maintenance, scrap recycling, reuse and treatment of the whole process of the "green", the life cycle of green cutting tool design. The key of green design is in the process of designing tool considering (product) the negative impact on the process environment, and its control in the smallest range or be completely eliminated. To this end, can establish green cutting tool life cycle design system model shown in figure 1.

The system model consists of four levels. The first layer is the target layer, to create "green resource utilization, energy saving tool, reduce pollution and Protect environment" as the goal; the second layer is the layer of technology content, structure design, including the selection of green materials green cutting tools, resources and energy utilization and protection of the ecological environment of four parts; the third layer is the process layer, design and development implementation of green design, which should be considered in the content production, use and maintenance and recovery processing of the main stage; the fourth layer is the main factors, which factors should be considered in the process of green design, including material, energy, cost, efficiency, safety, quality, service life, environmental impact.
