Numerical simulation of the glass screen lapping

Nowadays, the grinding disc design of big-screen glass screen follows the grinding disc design concept and equation of small-screen glass screen, so the entire glass screen surface was unable to be grinded uniformly and smoothly. Though the drive of the lapping mechanism is constant, it is difficult to describe its motion and set up a mathematical model for the constant dynamic contact between the grinding disc and the glass screen. The grinding disc movement locus and parameter of any time step can be obtained through kinematics simulation. Combing the removal rate, mapping the parameter of operation condition for discrete plane motion into a 3D space, substitute several quasi-static models for the lapping process and solve the grinding disc surface design by scattering the continuous lapping process. A simulation model is established though the understanding of the actual lapping process. After the simulation, revise the numerical simulation model by comparison between the simulation result and the actual result, and then simulate again, thus the simulation for the glass screen lapping process is realized.
