Nowadays , the machining center carries through the precision inspection only following the fixed coordinates " axes , which can not completely reflects the real error of the spacial position of the practical machining outside the axes and leads to having no the directive relation between the inspected precision and the practical machining precision . so , this paper introduces that the error factors of influencing workpiece ' s outline on machining and carries out the solid inspection of every spot ' s error inside the workaround on the horizontal machining center 本文针对当前加工中心仅沿固定的坐标轴线进行精度(含几何精度和定位精度)检验,并不完全反映轴线外实际加工的空间位置真实误差,导致检出精度与机床实际加工精度无直接对应关系的现状,论述了加工时影响工件型面轮廓精度之加工中心的误差因素,对加工中心实施其工作区内各点误差的立体检测。
