Abstract: The wear resistance of workpieces can be significantly improved by spraying wear-resistant coatings on their surfaces. However, during subsequent grinding, the contact interface between the coating and substrate (heterogeneous materials) causes discontinuous heat conduction, leading to thermal stress. Thus, it is necessary to set reasonable grinding parameters to strictly control the temperature at the coating-substrate interface. The temperature control of the coating-substrate interface during high-velocity oxygen fuel (HVOF) coating grinding was focused on, and multi-pass grinding parameter planning software was developed. Firstly, an empirical formula for tangential grinding force was obtained by fitting orthogonal experimental data, revealing the influence of grinding wheel linear velocity v_s, feed rate v_w, and grinding depth a_p on grinding force. Secondly, a grinding heat simulation model was established using Ansys based on the moving heat source theory and triangular distribution heat source model. A relational model was analyzed to link the interface temperature of double-layer materials with grinding parameters and coating thickness. Finally, grinding parameter planning software was developed to maintain constant interface temperature during multi-pass grinding. Testing and verification showed that the software operation results met expectations.
