We expound the finite element simulation and the key points of metal turning by the material properties of the stem in this paper, and select the proper material constitutive equation, then use the adaptive meshing technique, and then finite element modeling was carried out on the valve stem in the professional finite element software Advantedge FEM. The optimization scheme we designed of finite element simulation for the valve stem through the finite element software Advantedge FEM, and we research the influence of the amount of feed and speed cutting process about the cutting force and the cutting temperature.

Micro-plastic deformation is produced on the surface of the laser cladding layer by micro-forging, and crack makes a change in cladding layer. In this paper, a finite element model with a simplified panel strain model elastic-plastic of stress and strain relationship and adaptive meshing technique was used to simulate laser cladding layer crack by using DEFORM-2D software. Laser cladding process of cracks by micro-regulation forging is simulated. Comparing to the measurement of crack width, the results show that micro-forging can make the surface of laser cladding layer the residual tensile stress to adjust compressive stress, and the micro-forging can significantly reduce or eliminate the laser cladding layer crack. Reasonable and effective regulation of high-frequency micro-forging can improve the surface quality in micro-cladding layer.
