Open porous structure is of great importance for metal-bonded grinding wheel but hard to realize with traditional hot pressing and sintering process. In this article, a novel design and fabrication method of porous metal-bonded grinding wheel is proposed based on triply periodic minimal surfaces and additive manufacturing. The control method of pore morphology is specifically studied in terms of pore connectivity constraint condition and parametric control equation. With control equation, the porosity, equivalent aperture, relative density, specific surface area and pore connectivity of porous structure can be accurately controlled and predicted under given design parameters. With additive manufacturing, porous metal-bonded grinding wheel with well-formed pores and firmly-embedded abrasives can be realized. The grinding test results indicate that the novel porous metal-bonded grinding wheel behaves better than electroplated wheel in terms of grinding force and specific grinding energy. The proposed method can realize the design and fabrication of metal-bonded grinding wheel with large porosity and open porous structure, so as to effectively improve the problems such as surface blockage and grinding burn.
