摘要
为提高壳体类零件的孔加工精度,提出了一种通过加工编程对立式加工中心几何误差进行补偿的方法。通过双频激光干涉仪对立式加工中心的定位精度和重复定位精度进行检测,并利用分析软件及其相关参数标准对检测后的数据进行分析,得到立式加工中心的定位精度和重复定位精度对零件加工精度的影响规律。进而提出通过零件加工程序对立式加工中心几何误差进行补偿的方法。通过实际加工,验证了所提方法的可行性,并且能够满足壳体类零件孔加工的精度要求,是一种快速、有效的误差补偿方法。
In order to enhance the hole machining accuracy of shell machine parts, a method was put forward by compensating geomettle errors of vertical machining center through machining program. Using dual-frequency laser interferometer to test the positioning accuracy and repositioning aeeracy of vertical machining center, using analysis software as well as relevant parameters to analyze post-processing data, and finally getting the influencing law of machining center positioning accuracy and repositioning accuracy on parts maehing accuracy. A method was put forward by compensating vertical machining center geometric errors through parts machining procedures. Through the practical manufacture,the feasibility of the present method was verified which could meet the requirements of hole machining accuracy of shell parts, and was proved that it is a quick and effective way for error compensation.
