Abstract: Based on the theory of metal plastic formation,the paper describes the elastio-plastic stress field in the metal cutting deformation zone in great detail.A criterion for predicting the surface work-hardening depth in low speed orthogonal cutting is determined.The numerical solution of surface work-hardening depth is obtained by simulating the machined surface formation process.

Key words: low speed orthogonal cutting, work-hardening, finite element method
