Latest Patents

Xumeng Cheng holds a patent for a "Variable-step-distance micro-milling repair cutter path generating method for damage points on the 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, Cheng creates a UG curve in UG software based on the mathematical model. This UG curve serves as the repair path for machining process simulation. The method effectively eliminates cutter marks with a constant period and enhances the KDP crystal's resistance to strong laser damage. He has 1 patent to his name.
