For a long time, Europe, America, and peting each other in the international market, and has formed an invisible front, especially along with the progress of microelectronics, puter technology, numerical control machine tool in the 1980 s after the accelerated development, has bee the big four international machine tool show in machine tool manufacturers from all over the world pete to show the focus of the advanced technology, for the user, expanding the market.Has been developing rapidly in recent years, our country numerical control industry, however, import machine of momentum remains strong, starting in 2022, China39。s first power for three consecutive years to bee the world machine tool consumption, machine tool imports the first big country, China machine host consumption as much as $ billion in 2022, more than 70% of all such equipment and the most features are dependent on imports. To see domestic CNC machine tools, especially in highgrade numerical control machine tool is still lack of market petitiveness, investigate its reason mainly lies in the depth of the research and development of domestic CNC machine tools is not enough, production level is still backward, lack of service consciousness and ability, lack of system application product promotion, Keywords: Numerical control machine tools 。Development trend。Security issues 目 錄摘 要 ............................................................................................................................IABSTRACT..................................................................................................................II第1章 緒 論 ..................................................................................................................1 我國數(shù)控機床的發(fā)展現(xiàn)狀 ..............................................................................1 國外機床的發(fā)展狀況 .....................................................................................1 SET因素分析 ...................................................................................................2 未來數(shù)控機床的發(fā)展趨勢 ..............................................................................2 本課題設計的可行性 ......................................................................................5 市場發(fā)展前景分析 ................................................................................5 相關技術分析 ........................................................................................5 本機床設計的目的,意義,主要思想 ..........................................................8第2章 方案設計 ............................................................................................................9 市場調查分析 ..................................................................................................9 .........................................................................................9 .......................................................................................11 .......................................................................12 數(shù)控機床創(chuàng)新設計指標分析 ........................................................................12 ...........................................................................12 ...........................................................13 ...........................................................................................14 產品需求重要性分析 ....................................................................................14 ................................................................................................15 ................................................................................................17 功能分類 ..............................................................................................17 功能實現(xiàn)方式 ......................................................................................18第3章 產品文化和使用環(huán)境狀況分析 ......................................................................19 ....................................................................................................19 ...................................................................................19 數(shù)控機床的發(fā)展趨勢 ..........................................................................21 ....................................................................................21 ....................................................................................24 ...........................................................................24 .............................................................................
