低密度CH泡沫微柱微细车削加工工艺研究

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

低密度多孔泡沫材料在高能密度物理、辐射运输、绝热成型研究中有重要应用,但该材料多孔易碎,加工难度大.在尖刃金刚石外圆刀具和尖刃金刚石切断刀具设计的基础上,利用精密车削微加工方法制备了激光惯性约束聚变(ICF)所需的各类低密度CH泡沫微柱,并详细讨论了切削加工条件、加工刀具集合参数、切断刀具几何参数、加工参数等对CH泡沫微柱车削加工的影响.

Low-density foams have important applications in high-energy density physics,radiation transport and adiabatic molding.However,it has high processing difficulty because of its porous and fragile properties.Therefore,two special diamond tools were designed and fabricated,which were used for turning of cylindrical surface and cutting.Variable 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 also discussed in detail.
