摘要
工件在机床上或者夹具中时,用作确定位置的基准称为定位基准,定位基准分粗基准和精基准。定位基准的合理选择直接影响着机械加工的质量与稳定性。
When parts in the machine tool or fixture,used as a benchmark to determine the location known as the locating datum.Locating datum points crude benchmarks and refined benchmarks.A reasonable choice for locating datum has a direct impact on the quality and stability of the machining.
