Primary Research of Bionic Design on Tools with Mouthpart of Larvae Long Horned Beetles

Bionic design is a new method in engineering design. The mouthpart of the larva long horned beetle and its tunnel in wood are discussed in this article. To improve the cutting properties and tool life are always the main aim of cutting tool design. The foreground of cutting tool design using the larva long horned beetle is discussed on the bases of the mouthpart maxillae of Aphrodisium sauteri (Matsushita) and the tunnel in Quercus myrsinaefolia. The research can also make direction at new tool material and tool geometry parameter design.
