【Abstract】 For the fine wood products in which the main body is relief,a key reverse-engineering technology including laser-scan and NC carving is proposed. Laser-scan can obtain massive data,a mean filter method is proposed to smooth the thousands of points and generate high-quality STL. Based on the STL,NC path is generated. The high speed carving technology of NC-carving for the relief products is divided into two phases: rough carving and finishing carving,and the machining parameters are put forward for them. Excellent 3D model can be acquired with the proposed smooth method. High efficiency can be achieved and the final wood products has fine surface.更多还原
