In this paper, material properties of the segment of the porous metal-bonded diamond grinding wheel were researched by finite element simulation. Segments were manufactured according to the design result and their elastic modulus was measured. The key points are as follows: The influence of the porosity on the elastic modulus was analyzed through a finite element method. In the FEM model, the design variable only includes the porosity, and the tetrakaidecahedron model is applied as the microstructure model of porous metal matrix. The corresponding porosity was decided in order to meet the requirement of the elastic modulus.
