摘　　要：利用加工的标准公差值和制造成本-公差关系模型,以装配功能公差、加工方法的经济公差最大极限为约束条件,运用库恩-塔克准则,来实现装配件成本最低的公差优化设计。通过实例分析计算验证了此方法的可行性。Based on the standard tolerance and cost-tolerance curve, a method to achieve cost optimized tolerance allocation is introduced in this paper. The method is to use Kuhn-Tucker condition with restriction of the assemble tolerance limits and piece part tolerance limits with related manufacturing method. The feasibility of this method is also illustrated in this paper with an example.
