高性能机械加工机床
2009。 PP 219-260
摘要
本章介绍了主要机床的设计,建造和测试方面实现高精度加工零件。不仅机床还加工过程本身是一个错误的部分源代码。因此,一个全面的看法的机加工要求。高精度机械设计所涉及的一些基本原理和方法,提出了进一步深入的研究。一个关键的因素是误差源识别,研究它们的物理原因和最终的不确定性关联。因此,装配误差,热生长,构件的变形和控制不精确的描述。在零部件和组件的错误是沿机器运动链的传播,产生较大的位置误差在刀尖的位置和刀具轴方向。齐次矩阵的使用是一个非常有用的工具,用于估计的误差传播。通过切削力引起的挠度变形工具和机器的另一个重要的误差源。不幸的是,变形是不可能避免的一些模型现在设置加工刀具路径选择器,这意味着最小的切削力误差敏感方向。施工后,就在机床交付给客户,精度验证和性能必须始终执行。描述现有的标准和程序,这是在本章的最后介绍了。
