This paper describes a new automated mesh generation system for micromachines whose sise range 10?? to 10?³ m. This mesh generation process consists of three subprocesses: (a) definition of geometric model, (b) generation of nodes, and (c) generation of elements. One of commercial solid modelers is employed for three-dimensional solid structures. Node is generated if its distance from existing node points is similar to the node spacing function at the point. The node spacing function is well controlled by the fuzzy knowledge processing. The Voronoi diagram method is introduced as a basic tool for element generation. Practical performances of the present system are demonstrated through several mesh generations for threedimensional micro actuators.
