Abstract
The improved cylindrical wet grinding temperature (ICWGT) model considering the lubrication effect of the grinding fluid is established and solved numerically. In doing so, the Newton–Raphson method is used to solve the hydrodynamic pressure of grinding fluid, and the fast Fourier transform (FFT) method is employed to accelerate the deformation calculation. Furthermore, the convective heat transfer coefficient (CHTC) is calculated based on the heat transfer theory, and the moving heat source method is adopted to obtain the grinding temperature. Meanwhile, the effectiveness of ICWGT is verified through the grinding temperature measurement experiment of alloy steel. Then, the cylindrical wet grinding temperature for alloy steel considering the lubrication effect of grinding fluid is studied and compared at varied grinding process parameter, and some rules are revealed.
