In many projects, peeling off timber skins is needed before the timber processing. The main purpose of the design is the 3D design and simple kinetic simulation to the machine part of the small timber barker with computer. Due to the advantage of computer, the time of designing, manufacturing and debugging of the prototype machine is greatly reduced. Therefore, cost is greatly reduced. After the analysis of the working principle and the preliminary design in this design, UG, the widespread application CAD/CAM software at home and abroad, is used to complete solid modeling of all machine parts of the small timber barker. And every part of the machine is assembled virtually. At last, the preliminary kinetic simulation is completed by the kinetic analysis department to simulate actual manufacturing process and analyze whether existing intervention or not. After the 3D design, AutoCAD software is utilized to protract the drawings and the assemble drawing, which makes this design closer to production and easier to be adopted.
