摘　　要：采用精度建模理论对转台误差建模,得到精度分配模型;用转台制造误差近似表示典型体误差。利用Matlab计算,在制造误差变化时转台精度的变化,做出曲线图,观察制造误差和直驱数控转台精度的关系;要求是制造成本最低和满足工作精度,从而对转台零部件进行精度分配。This paper presents precision distribution model by rotary table error model based on the theory of accu- racy modeling and approximates the typical body error from manufacturing error. The changes of the rotary table accuracies when manufacturing error changes are calculated and graphed by Matlab. And the relations between manufacturing error and the precision of direct drive NC rotary table are analyzed. Finally, precisions of the parts in rotary table precision are assigned from the lowest cost and satisfy the manufacturing accuracy.
