摘要
加工中心上模具钻孔采用无人值守加工可提高生产效率。在对无人值守条件下模具钻孔精度问题及其影响因素进行分析的基础上,提出相应的改进措施,包括优化钻头结构和切削方法等,以促进无人值守孔加工的顺利实施和质量提升。
The efficiency of die hole drilling based on MC can be improved by adopting unattended processing.The inaccuracy and its influencing factors of die hole drilling in unattended conditions were analyzed and the corresponding improvement measures which help the smooth implementation and quality improvement of unattended drilling were put forward,such as optimizing the bit structure and cutting method,etc.
