摘要
在航空制造业中,为了减轻工件的重量,大量使用薄壁结构零件。对于这类工件,改进工件的夹具布局能够有效地减少工件的变形。本文通过对弧形薄壁件铣削加工夹紧点的位置进行优化来减少工件的变形,并提出了6条启发式规则。这些规则根据各区域内工件的最大变形,依次确定各夹紧点的移动方向,具有较快的优化速度。
In aerospace industry, many thin- walled workpieces are used in order to reduce the weight. For these workpieces, the deformation can be reduced through optimizing fixture layout. In this paper, the clamping points are optimized during milling process of thin-walled arc workpiece. Six heuristic rules are proposed. Based on the maximal deformation of each region, these roles decide the movement direction of each clamping point, having a faster optimizing speed.
