Study on the Time-varying Characteristics for Deformation and Stress of Turning Work-piece

Abstract

Based on the orthogonal plane model theory, a two-dimensional finite element model of turning work-piece was established. Moving load was applied to work-piece by using APDL language. This paper carried out the simulation analysis on the Time-varying characteristics of the turning work-piece by using the birth and death element technology of ANSYS for the removal of the chip. The research shows that the work-piece is the most difficult to be cut in the initial stage of turning, and the stress value is the maximum at this moment. The stress obeys stress yield criterion of the work-piece after entering the stable turning stage. The deformation curve of the work-piece is nearly a half parabolic distribution.
