A mathematical model in the grinding technology of explosion - proof surface is worked out to find out vibration characteristics , amplitude and phase , and educe the relation curve between shape error and technical parameter 进而讨论箱体零件加工工艺过程误差转换模型、形状精度特征、传递图、描述方程、误差转换结构图;提出防爆面磨削工艺系统的数学模型;求解出振动特性、幅值和相位,得出了形状误差与工艺参数的关系曲线。
This task adopts the instrument that realizes the examination , analysis and compensation in the process , to increase the movement accuracy of the numerical control system . the structure is simple and the result is remarkable . it spread general numerical control system 本课题采用计算机辅助误差测控仪实现加工过程误差检测、分析及补偿的方法来提高开环数控系统的运行精度,结构简单、效果显著,可推广到一般的开环数控系统上。
Posteriorly , it is all positive of the science , education , civilization , sanitation expenditures in its configuration of the local expenditures . so there are very important to regions economy . the administrational expenditure is all negative , which interprets that it has exceeded its best scale 由于体制背景、经济数据的可获得性以及指数平减过程误差的缘故,本文在分析经济变量之间关系的经济计量检验方面存在一定的偏误,但这并不影响研究结论的总体可靠性。
