Miniaturisation generates necessity of micro-parts production. Micro-scale means closer tolerances and better surface roughness. These requirements can be achieved with metal forming processes but under high pressure and sufficient relative sliding distance between tool and workpiece surface. It makes such process galling prove. This tendency increases with diminishing of component dimensions. Literature search and previous investigations shows that implementation of vibrations might be a solution for limitation of galling tendency in microforming. The group of so called “reference micro-parts” has been chosen as a representation of micro-products. The tooling system for vibration-assisted microforming of referenced parts has been designed. Vibrations are performed with vibrators based on stacked ceramic multilayer technology, which provides accurate frequency and amplitude control. Proposed reference micro-components and designed laboratory system can be used for investigations of technological parameters for utilisations of microforming. After laboratory investigations it is intended to design industrial system working on same principles. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR] |
