CNC technology has a wide range of applications in the woodworking machinery industry, in the face of the huge demand in the market, many wood products, such as the production arm of the sofa to the development of high-volume, high-precision direction. But high-quality, high-performance arm of the sofa equipment remains abroad there is a big gap in the use of high-end products, the domestic furniture industry also rely on imports to some extent, restricted the development of the arm of the sofa equipment in China and the whole furniture industry. Therefore, it is urgently needed to design, research and development of a new arm of the sofa CNC machine tools, providing a new way to meet the market demand for the development of woodworking machinery. In the design of the program, the machine uses a multi-station, milling machining, three-axis linkage processing operation mode. , Symmetrically arranged on the work bench is equipped with four fixture. The upper crossbar with the gantry structure, the gantry across both sides of the workbench, and movement through the sliding guides on the work bench, and the X direction feed. Main transmission system design for the two sets of side-by-side mounted on the gantry stand, stepper motor driven, overall reciprocating motion along the upper beam, feed on the Y direction. Spindle components using electric spindle structure, the rolling screw nut institutions driven, feed on the Z direction. Function of the overall structure of the arm of the sofa CNC milling and its components was introduced and gave a detailed description of the design of the overall structure of the machine, on beams gantry bracket is the carrier of the main drive system, ANSYS software simple finite element analysis. A brief introduction to the Ming Dragon Sail CNC system. Using mathematical approximation, spline function, using MATLAB software interpolation calculation, output interpolation curve of the arm of the sofa, a mathematical model, and the standard spline interpolation curve fitting. Based on the arm of the sofa after the final fitting spline curve, manual preparation of the program and the trial cutting experiments on the machine. This station machine has finished, and a variety of debugging, test cut on the workpiece, and to good effect. The subject is horizontal issues, on the one hand to provide production services for the enterprise, has practical significance, on the other hand, within the field of CNC woodworking machinery milling point attempt, the machine tools successfully for our woodworking machinery NC provide little valuable reference.
