Study on the Cutting Performance Improvement about Woodworking Forming Cutter that is Assembled by Circular Saw Blades

Abstract

For the difficult problem of hard wood milling groove on the mini-type multipurpose woodworking machine tool, a woodworking forming cutter that was assembled by the circular saws, shaft sleeve and flat gaskets was designed. The woodworking forming cutter had a special structure characteristics of the multiple narrow blades combination instead of double wide blades when assembling, it’s saw tooth showed a longitudinal dislocation arrangement, and a whole cutting edge was composed of the corresponding tooth blades on each saw component. The larger rake angle was adopted to improve the cutting performance of saw blade, and saw-tooth was planed after tooth profile optimization to improve the durability and the service life of it. In the milling groove of hard and soft wood, the cutting force was reduced by more than 6 times and the feed speed increased by more than 3 times, because of the special cutter with block straight cutting edges.
