摘要
使用三座标测量仪测量荫罩的曲面时应对测试杆球头半径加以修正,引出修正的计算公式,从而获得三座标测量仪原有的测量精度。并根据这些正确的测试数据,介绍了荫罩曲面拟合的方法,以保证制造出合格的冲压模具。
In this paper the correction of ball head's radius of surveying rod is invesitigated and computing
formulas of correction are derived,this assures the original measurement accuracy of the instrument.
Moreover,according to the above corrected data, a fitting method of the shadow mask surface is intro-
duced in order to turn out qualified mould.
