Abstract
In recent years, the demands for micro components are increasing in various industries. Mechanical micromachining is one of the best fabrication methods for creating micro parts with complex dimensional features. However, in micromachining, the material microstructures, such as grain size, grain boundary, and crystallographic orientation, have significant influence on the machining process and the part’s quality. In this paper, a set of micromachining experiments were conducted on oxygen-free copper to investigate cutting force and burr formation affected by the material microstructures. The results showed that both the crystallographic orientation in single crystal material and the grain size in polycrystalline material have great effect on the cutting force and the burr formation.
