Research of Bionic Design on Tools with Chewing Mouthparts of Insects

Bionic design is a new method in engineering design. The mouthparts especially for the chewing ones of the insects are discussed in this article. To improve the tool life and cutting properties are always the critical for the cutting tool design aim. The foreground of cutting tool design is discussed using the mouthpart of insect as bionic design object. The basic structure of the chewing mouthpart, type of mandibles, geometry, hardness, and element contained, moving mechanism and so on will be described. The research can also make direction at new tool material and tool geometry parameter design.
