Abstract: Material removal processes of a structure are disclosed. These processes can define several features. For example, metal structure can include an interior recess surrounded by a sidewall. The structure can further include a base portion integrally formed with the sidewall. The sidewall can include an opening extending through the sidewall and into the interior recess. The sidewall can undergo a material removal process to include multiple curved regions. The sidewall, the first curved region, and the second curved region can be polished to include a reflectivity different than a reflectivity of an exterior region of the base portion. A single multi-axes lathe having multiple spindles performs several material removal processes under a continuous machine cutting process. The spindles may include clamping features that allow a first spindle to perform a first operation then pass the metal structure to a second spindle. Additional processes include lapping, polishing, and linear brushing.

Abstract translation: 公开了一种结构的材料去除方法。 这些过程可以定义几个特征。 例如，金属结构可以包括被侧壁包围的内部凹部。 该结构还可以包括与侧壁一体形成的基部。 侧壁可以包括延伸穿过侧壁并进入内部凹部的开口。 侧壁可以经历材料去除过程以包括多个弯曲区域。 侧壁，第一弯曲区域和第二弯曲区域可以被抛光以包括不同于基部的外部区域的反射率的反射率。 具有多个主轴的单个多轴车床在连续机床切割过程中执行多种材料去除工艺。 主轴可以包括允许第一主轴执行第一操作然后将金属结构传递到第二主轴的夹紧特征。 其他工艺包括研磨，抛光和线性刷涂。

Abstract: By constructing packaging or cushioning components with a cellulose-fiber foam and uniquely blending relatively longer fibers serving as mechanical structure with refined chemical fibers serving as a bonding mechanism for the relatively longer fibers together, a lower density, energy absorbing, and resilient cellulose-fiber foam is disclosed. Some cellulose-fiber foam components additional do not require stand-alone foaming agent or surfactant.
