本文提出了一种独特的测试件，用于评估五轴加工中心的加工性能。NAS 979标准规定的截头圆锥体已被用作40多年的试验件。本文提出用半顶角为15 °的截棱锥代替圆锥台作为检验加工性能的试件。截头四棱锥必须安装在夹具的斜面上，该夹具安装在加工中心的旋转工作台上，以便在五轴同步控制下进行加工测试。因此，准备了两种不同安装角度的夹具用于实验。利用安装在主轴头上的LVDT传感器在工作台上测量铣削加工后的四个侧面的轮廓。还在坐标测量机上测量试样的侧表面的轮廓形状。从两种测量数据中可以看出，在机测量可以评定各侧面的直线度、相邻面间的垂直度和平行度，还可以检查倾斜转台的螺距误差和侧隙。与圆锥台试验方法相比，该试验方法提供了更多的信息。
This paper proposes a unique test piece for evaluating the machining performance of five-axis machining centers. A cone-frustum specified by NAS 979 standard has been used as a test piece over 40 years. In this paper, a truncated square pyramid with a half apex angle of 15 degrees is proposed as a test piece for checking the machining performance instead of the cone-frustum. The truncated square pyramid has to be installed on the slope of a fixture which is mounted on the rotary table of the machining centers in order to conduct the machining test under simultaneous five-axis control. Thus, two kinds of fixtures with different mounting angle were prepared for the experiment. The profiles of four side surfaces finished by milling were measured on machine table by an LVDT sensor which is fixed on the spindle head. The contour form of the side surfaces of the test pieces were also measured on a coordinate measuring machine. It is found from both measurement data that the straightness of each side surface, the squareness between adjacent surfaces as well as parallelism can be evaluated by on-machine measurement, and also pitch errors and backlash of tilting rotary tables can be checked. This test method gives much more information compared with the cone-frustum test method.
