At present, the green cutting technology to dry cutting and high-speed cutting mainly. When green design tool technology, should meet the following basic requirements:

To meet the dry cutting, high speed cutting for cutting tools requirements, green tool material should have high strength, high stiffness and good heat resistance, impact toughness and other mechanical physical properties. Some of the existing tool materials such as ceramics, cbn, high-performance hard alloy etc has good heat resistance, abrasion resistance, etc., it can be used for the manufacture of green tools.

Dry cutting, high speed cutting can significantly improve the cutting zone temperature, increasing the friction between the tool and chip easily BUE, increased tool wear. In order to improve the cutting edge of high temperature, wear resistance, may be appropriate for the tool surface coating (coated tin, tic, al2o3 coating, etc.), in order to reduce cutting forces and cutting power play, minus small tool and chip frictional resistance, barrier cutting heat, reduce tool wear and extend tool life role.

Chip and heat is dry cutting, high speed cutting processes important issues to be resolved. To improve processing quality, longer tool life, the flute structure to deal with green tool to optimize the design to ensure smooth chip removal, heat rapidly.
