Description
Summary:A heterogeneous material with a certain periodic microstructure may have specific properties, such as negative Poisson’s ratio and zero thermal expansion coefficients, which can satisfy some requirement of high technology. However, currently research about how to fabricate such 3-D periodic microstructures is rarely reported in the published literature and only some 2D fabrication procedures were developed. To fabricate such components, a hybrid-layered manufacturing process has been developed and applies spraying, engraving, and refinishing technologies, among which the engraving is the key technology for generating the voids of periodic microstructures with their required dimensions and accuracies. To implement such an accurate engraving, it is important to study its engraving behavior. This paper establishes a behavior model of the engraving operation and performs its behavior simulation, thus providing a reliable basis for future practical manufacturing.
