YAG laser processing CNC machine design

Abstract：The graduation design topic is YAG laser processing CNC Table design. Numerical control worktable is the main component of YAG laser. It determines the laser machining accuracy, its each direction of travel to meet the technical indicators, the transmission system should be able to meet at a given condition has a good three coordinates movement and self-locking. The transmission system has the advantages of simple structure, convenient manufacture, repair. Assembly and spare parts, the design should meet the standardization of parts, components and serialization of products and machine tool variant requirements. In the numerical control drive system function, working principle is analyzed, according to the task the system requirements and servo motor and ball screw design, the transmission system adopts the structural form of the argument, and the structure design and calculation of optimization.
