| Abstract: | Considering the NC processing errors of satellite pressure vessel head plate,the whole machining process is analyzed in this paper.To reduce the processing errors,several measures are taken,such as adding destressing procedure,internally controlling assembly accuracy of internal spherical surface and clamping fixtures,optimizing machining tools and cutting parameters,and compensating tool arc wear.Finally,the products meet all requirements. |
