Study on techniques of Elastic clamping and plastic cutting

Deformation problem is solved, using approach of elastic clamping in metal machining process, The way eliminate deformation of part that was given rise to because of very large clamping force; It Improves the accuracy of parts. Plastic cutting is the use of plastic deformation behavior of materials, It not only was used to control cutting force to reduce energy consumption in metal processing, and as much as possible to eliminate the work hardening phenomenon, but also minimize the possibility of plastic deformation of tool, increased tool life. Used the tensile test of materials of 2Cr13, It was on the basis of determining limit values of the clamping force and cutting force in the cutting spindle; It was based on the experimental stress values; through test of cutting of spindle of materials of 2Cr13. It was verified that technology of the elastic clamping and plastic cutting not only can greatly improve of accuracy and efficiency of machining of the parts, but also as the necessary conditions of realization of part of trace, high-speed, precision cutting.
