This research focuses on the development and evaluation of green wood chipper cutting assembly(herical drum cutter and feeding system). The waste wood dominates a lot of weights among industrial waste. Recycling of wood waste is very important in environmental problem solving and energy saving. Green wood chipper is needed for this purpose. The traditional chipper drum has an orthogonal cutting(2D) condition considering of saw cutter and wood cutting pattern. Additional disadvantage of this type include big cutting resistance, high cost of cutting power and extreme occurrence of vibrations. To improve this shortcoming, a helical type drum with an oblique cutting(3D) condition and feeding system are developed, this new parts decreased the vibration and cutting resistance of chipper and also improved productivity and chip porosity.
