Research on pocessing technology of low-density CH foam micro-column

Abstract:

Low-density foams have important applications in high-energy density physics, radiation transport and adiabatic molding. However, it is very difficult to make these materials into tiny parts for their porous and fragile. Therefore, two special diamond tools were designed and produced, which were used for turning of cylindrical surface and cutting. Kinds of low-density CH foam micro-column used for ICF were machined by precision turning micromachining technology. The effects of cutting conditions, geometry parameters of diamond tool and machining parameters on the forming of CH foam micro-column were discussed in detail.
