Latest Patents

Mingjun Chen holds a patent for a "Variable-step-distance micro-milling repair cutter path generating method for damage points on surface of optical crystal." This method involves establishing a mathematical model of a repair profile and determining discrete contact points between a cutter and the repair profile. The process utilizes a GPR path generating method to control the movement trend of a pseudo-random path. By interpolating the cutter position control point set into a spatial curve using a NURBS modeling method, the method effectively eliminates cutter marks with a constant period. This innovation enhances the ability of KDP crystals to resist strong laser damage. He has 1 patent to his name.
