摘要
根据实际工作经验,从优化加工工艺、选择合适的加工设备和刀具、优化检测方法等几个方面,论述了如何保证壳体6H7腰形孔相对于K基准的对称度要求0.02mm,从而提高壳体腰形孔对称度的合格率。
Based on the practical experience,the paper discusses the symmetry 0.02mm relative to datum K for 6H7 waist-shaped holes in the case in the terms of optimization of maching process,proper choice of processing equipment and optimization of test methods,thus improves the qualified rate of waist-shaped hole symmetry.
