符合组件的质量要求对于整个产品的功能至关重要。对于具有端面铣削面的零件，工件边缘的表面质量和形状非常重要。通常，这些面接管密封面的功能，其中存在对表面完整性和毛刺形成的高要求。为了确保所需的工件质量，现在通常需要额外的去毛刺工艺。为了避免去毛刺，修改加工工艺是一种很有前途的方法。在这项研究中，工艺冷却对工件质量的影响进行了调查。使用这种方法，预计会产生两种效果。冷却用于最小化由工艺热产生的流动应力的减小，这导致较低的可成形性。第二个效应与用于通过碎片的变形和断裂去毛刺的雪风的动能有关。使用二氧化碳工艺冷却，可提高表面质量并最大限度地减少毛刺的形成。(C)2010 Elsevier B.V.保留所有权利。
The compliance with the quality requirements of components is essential for the functionality of the whole product. With respect to parts with face-milled faces, the surface quality and the shape of the workpiece edges are of great interest. Frequently, these faces take over the function of seal faces where high demands on the surface integrity and burr formation exist. To ensure the workpiece quality that is required, nowadays additional processes for deburring are often necessary. To avoid deburring, the modification of machining processes is a promising approach. In this study, the influence of process cooling on workpiece quality is investigated. Using this approach, two effects are expected. The cooling is used to minimize a reduction of flow stress generated from the process heat, which than leads to a lower formability. The second effect relates to the kinetic energy of the snow blast for deburring by deformation and breakage of the burrs. Using a process cooling with carbon dioxide, the surface quality is enhanced and the burr formation is minimized. (C) 2010 Elsevier B.V. All rights reserved.
