A new linear structured light module based on the Micro-Electro-Mechanical System (MEMS) two-dimensional scanning micromirror was designed and created. This module consists of a laser diode, a convex lens, and the MEMS micromirror. The laser diode generates the light and the convex lens control the laser beam to converge on a single point with large depth of focus. The fast scan in horizontal direction of the micromirror will turn the laser spot into a homogenous laser line. Meanwhile, the slow scan in vertical direction of the micromirror will move the laser line in the vertical direction. The width of the line generated by this module is 300μm and the length is 120mm and the moving distance is 100mm at 30cm away from the module. It will promote the development of industrial detection.
We simulated the process of grinding glass-ceramics with the finite element simulation method. During the simulation, we considered the impact of changes in various process parameters on the grinding and analysis the simulation results of the residual stress at last. The target of this research is to provide some basic reference for the choice of the glass-ceramics grinding process parameters.
