    摘要
  • 摘要: 切屑厚度的求解是进一步研究切削过程机理以及实现加工过程仿真的基础.针对面铣刀正交车铣加工过程进行了研究,通过对刀刃轨迹进行简化,推导了计算几种不同形状面铣刀切屑厚度的统一公式,并结合几组具体实例与通过数值方法求得的切屑厚度进行了对比.最后,应用所建立的切屑厚度计算公式实现了对正交车铣加工切削力的仿真,并在车铣复合机床上进行了实验验证.对比仿真实例及切削力实验结果显示所给出的切屑厚度计算模型具有良好的精度和较高的计算效率.同时,统一的表达形式也使得所提出的方法适合于正交车铣加工过程通用仿真软件的开发,具有较大的工程应用价值.

     

    Abstract: The computing of uncut chip thickness is the basis for further studying the cutting mechanism as well as simulating the cutting process. The research about orthogonal turn-milling operation with inserted cutters was focused on. By simplifying the trajectory of cutting edge, the uniform formulation to calculate uncut chip thickness for cutters with different shapes was derived and then compared with the numerical method through several examples. Upon the presented formulation of uncut chip thickness, the cutting force in orthogonal turn-milling operation was predicted and a validation experiment was carried out on a turn-milling machine tool. Both the comparison examples and the result of cutting force prediction show that the presented approach can provide a solution for the calculation of uncut chip thickness with good accuracy and high computation efficiency. Due to the uniform expression, the proposed approach is suitable for the development of general simulation software for orthogonal turn-milling process and thus has potential value in engineering practice.
